He Absolutely Destroyed The Event For The Win | Myer Stump AMSOIL UCC 2026 CHAMPION

The “Amsoil Ultimate Call Out Challenge 2026” is a competition event in the diesel performance world. The host frames it as a milestone where he won in his rookie year and “swept,” implying a head-to-head style format.

Power Driven is referenced as the host’s workplace and as the shop where he started “messing with” parts or setups. In diesel performance, companies like this typically build and tune trucks, supply performance components, and support customers competing in events.

“Dodge Ram” refers to the Ram pickup truck line from Dodge (now Ram Trucks). In diesel performance circles, Ram trucks are popular because the Cummins diesel and the truck’s drivetrain are well-supported for tuning and competition.

“Turn up” is diesel-performance slang for increasing engine output through tuning and calibration changes (often affecting fuel delivery and boost). The host says that once he started fixing the truck, he realized how easy it was to “turn up,” meaning the truck responded well to modifications.

In this context, UCC is an event series for diesel trucks—short for a competition where diesel builds are judged and/or raced. The hosts are talking about winning and championships tied to that event, so it’s a named motorsport/competition acronym rather than a generic term.

“Mechanical injected” describes a diesel fuel system where fuel delivery is controlled mechanically (typically via a mechanical injection pump) rather than electronically. That usually changes how the truck responds to tuning and how power is made and controlled.

Two-wheel drive (2WD) means power is sent to only one axle, typically the rear axle on many trucks. In diesel performance builds, switching between 2WD and 4WD can dramatically change traction and how effectively the truck can put power down.

“NB 4500” refers to the NV/“NB” 4500-series manual transmission used in GM diesel applications. It’s a specific gearbox people choose because it can handle diesel torque better than many stock setups and is common in swap builds.

“67 common rail” refers to a 6.7-liter Cummins common-rail diesel engine swap. Common-rail means the engine uses a high-pressure fuel rail to deliver fuel to the injectors, which is a major part of why these engines respond well to performance tuning.

“Auto” here means an automatic transmission, as opposed to the earlier manual setup. In diesel performance trucks, transmission choice affects shift behavior, durability under load, and how well the truck manages torque.

This describes a chassis swap onto a GM Duramax-based frame, meaning the build uses the structural platform from a Duramax-equipped truck. Doing this is common in diesel swap projects because it provides a proven frame and drivetrain mounting points for the new engine/transmission.

Four-wheel drive (4WD) sends power to both axles, improving traction and stability—especially during hard launches or on low-grip surfaces. For high-torque diesel builds, converting to 4WD is often a key step to keep the tires from spinning.

“Low” in truck builds usually refers to ride height—how lowered the suspension is compared to stock. Lowering can change handling and stance, but it can also affect ground clearance and drivability.

In a build or racing program, “scrapped” means the team decided not to keep using that truck and effectively retired it from the project. That usually happens when the platform has major issues, repeated failures, or doesn’t justify the cost/time to fix versus starting fresh.

On many diesel performance builds, the “P pump” refers to the Bosch-style inline fuel injection pump used to pressurize and meter fuel for the engine. In a high-power truck, pump condition and calibration strongly affect how much fuel the engine can deliver under load, which then drives power and reliability.

“800 horse” is shorthand for about 800 horsepower, a measure of engine output. In diesel drag-racing contexts, horsepower is often used as a quick indicator of how aggressive the fueling/tuning is and whether the build is reaching its intended performance target.

In drag/race circles, a “roller” is a partially built chassis—typically with the body and suspension, but without the complete powertrain. Buying a roller lets you swap in the engine/transmission setup you want and build the truck around it.

Traction is how well the tires can grip the road without spinning. In drag racing, traction is critical because the engine’s torque only turns into acceleration if the tires can hold it—otherwise you get wheelspin and slower times.

A turbocharger uses exhaust gas to spin a turbine that forces more air into the engine, which can dramatically increase power. Diesel engines often rely on turbocharging because it helps them make more torque without needing a larger displacement.

In diesel performance talk, “a thousand” usually refers to roughly 1,000 horsepower (or sometimes 1,000 lb-ft of torque). The host is describing how the top trucks moved from chasing that first 1,000 mark to making it routinely, then pushing toward 2,000–3,000.

“Shooting turbo chargers out of the hood” is a vivid way to describe catastrophic turbo failure under extreme boost and heat. On heavily modified diesel drag builds, a turbo can let go (often from overspeed, oil starvation, or weak mounting), and the turbine/compressor assembly can physically break through the hood.

Mechanical injection refers to a diesel fuel system where fuel delivery is controlled mechanically (via linkages and pump-driven components) rather than electronically. It’s often discussed in performance circles because it can be tuned for high fueling and can behave differently under extreme boost and power levels.

Cummins is the diesel-engine brand most associated with heavy-duty pickup and truck performance culture. The host uses “Cummins 101” to mean the foundational knowledge and common engine platform in this scene.

“AFC live” is an aftermarket diesel tuning/control approach associated with adjusting fueling on certain mechanically injected setups. In practice, it’s used to manage how much fuel the engine gets (and when), which strongly affects power, smoke, and drivability.

In diesel performance circles, “2000 horsepower” is a shorthand for extremely high engine output, typically achieved with major fueling and airflow upgrades plus careful engine management. When someone says a build “blew up” around that number, they’re usually talking about the engine or drivetrain failing under the stresses of that power level.

A “daily” in this context means the truck is driven regularly for everyday use, not just for pulls or track days. Running a 1200-horsepower diesel daily implies the builder prioritized durability and drivability—keeping it reliable enough to live with while still making extreme power.

“Blew up the engine” is enthusiast shorthand for catastrophic engine failure—something inside the motor fails under load, often from overheating, lubrication issues, or parts not surviving the power and fueling demands. In high-output diesel builds, this is commonly tied to the stresses of repeated hard pulls and aggressive tuning.

Swapping in a “new engine” after a failure is a common approach in extreme diesel builds: you replace the failed long block and then return to a “similar setup,” meaning the same general power strategy (fueling/airflow goals and supporting hardware). The key idea is that the builder is iterating on durability while keeping the performance direction.

In this context, “overdrive” is being used to describe the drivetrain behavior where the rear end starts to rotate when the throttle is applied. It’s essentially the truck getting into a traction/handling situation that feels like it’s “too much” for the available grip.

Adding concrete to the rear bumper is a crude form of ballast to increase rear-end weight. More rear weight can increase traction during hard launches by improving weight transfer and reducing wheelspin, but it’s also a safety/handling compromise.

Preload is the initial amount of force placed on a suspension component (often springs or coilover setups) before the truck is loaded. More preload can change ride height and how quickly the suspension compresses, which can improve traction and “hook” during hard acceleration.

“Stance” refers to the truck’s attitude/ride height and how level or squatted it sits under load. In drag or hard-acceleration setups, changing stance (often via suspension settings like preload) can affect weight transfer to the rear tires and improve traction.

“Hook” is drag-racing slang for traction—how effectively the tires bite and the truck accelerates without spinning the tires or sliding the rear end. Suspension and weight-transfer changes (like preload/stance) are often tuned specifically to improve hook.

“Daily driven street truck” means a vehicle that’s set up to be used on public roads as a normal commuter, not just for events. In this context, it contrasts with a purpose-built competition setup, implying changes to power, cooling, and drivability to survive event conditions.

“Horsepower” is a measure of engine power output, commonly used in drag and diesel performance to describe how much work the engine can do. The speaker uses the jump from 1,200 to 3,600 horsepower to emphasize how big the performance step is between street and competition configurations.

A “competition vehicle” is a car or truck prepared specifically for racing or timed events, often with upgrades that prioritize repeatable performance over everyday comfort. Here it’s used to describe the jump from a street setup to an event-focused build capable of much higher output.

“10 mile an hour” is likely referring to a rule/condition tied to the event’s run category or staging requirement (for example, a minimum vehicle speed or a specific test protocol). In performance competitions, these kinds of constraints define what counts for records and how runs are judged.

“Southwest win” appears to be a transcription of “Southwest wind,” referring to wind direction during the run. Wind direction and speed can affect traction and aerodynamic drag, which is why competitors often mention it when discussing whether a record “counts.”

Fuel injection refers to how an engine meters and delivers fuel into the combustion process. In diesel performance, the specific injection strategy (like common rail vs older systems) can strongly influence combustion, power, and how the truck performs in competition.

“Winner circle” is a motorsports term for the top finishers—typically the podium or the group of drivers/teams recognized at the end of a race. The host is using it to contrast what common-rail vs mechanical trucks tend to achieve in their event.

Sled pulling is a motorsport where a vehicle drags a weighted sled over a track, and the goal is to pull the most weight or go the farthest. Diesel competitors often tune for high traction and sustained torque rather than short bursts of speed.

Drag racing is a straight-line motorsport where cars accelerate over a short distance to achieve the best elapsed time or top speed. In diesel performance circles, it strongly rewards drivetrain strength and fuel/air control for repeated hard launches.

NHRDA is the National Hot Rod Diesel Association, an organization that sanctions diesel drag racing events and classes. When someone references NHRDA, they’re usually talking about specific competition rules, venues, and competition categories.

“Four nineties” is drag-racing shorthand for running in the 4.90-second range for the quarter-mile elapsed time. It’s a performance benchmark used to describe how fast a car or truck is at the track.

A “dino rig” is a purpose-built dynamometer setup used for testing and tuning. The idea is that you can swap components or calibration quickly to chase peak power, then return the vehicle to the next configuration for testing or competition.

“Solid block” refers to an engine built around a robust engine block (as opposed to a more fragile or lightweight setup), typically meaning a stronger foundation for extreme power. In diesel performance, it often implies internal engine durability work to survive high boost and fuel delivery.

“Timing” here refers to when the engine’s combustion event is triggered relative to crankshaft position (often discussed as injection timing and/or ignition timing). The host describes tuning that “ramps in” timing and then compensates for nitrous, which is crucial because timing changes combustion efficiency and how much cylinder pressure you can safely make. On a dyno, timing can be set differently for different operating points.

“Nitrous” (nitrous oxide) is an aftermarket power-add system that injects oxygen-rich gas to increase combustion potential. The host is discussing how nitrous changes the tuning strategy—especially timing and fuel delivery—because the engine needs fuel to burn quickly and completely under higher oxygen availability. They also connect nitrous to droplet burn rate and cylinder exposure as the piston moves down the bore.

Injection pressure is how strongly the diesel fuel system pushes fuel into the combustion chamber. The host claims the injection pressure is “super low,” which leads to “big old droplets” that can’t burn as fast. In high-power setups (especially with nitrous), faster combustion is critical, so low injection pressure can become a limiting factor.

The “bore” is the cylinder’s inner diameter in an engine. The host uses it to explain combustion timing: with big nitrous, you want the fuel to burn quickly before the piston travels far down the bore. If it doesn’t, the combustion event can become less efficient and can expose more of the cylinder wall to conditions that aren’t ideal for power production.

“Northwest Dyno circuit” refers to a dyno event location/series in Utah where diesel builds are tested. Dyno sessions are used to measure power and tune fueling/boost for repeatable results.

AFR (air-fuel ratio) is the balance between how much air and how much fuel the engine burns. Lower AFR numbers mean richer mixtures (more fuel), which can be used strategically on diesel builds for power, but it must be managed to avoid overheating or excessive soot.

“Confidence to make the power on the dyno” refers to the tuning/strategy readiness to hit a target output safely under controlled test conditions. Dyno confidence usually comes from prior data, repeatable fueling/boost control, and knowing how the engine responds under load.

A “bearing mod” is an aftermarket modification to the engine’s bearing setup to improve durability under high load. In diesel performance builds, it’s often aimed at reducing wear and preventing failures when power and cylinder pressures are pushed hard.

“Lube mods” are lubrication system modifications intended to improve oil flow, cooling, and film strength under extreme conditions. On high-power diesel builds, better lubrication helps prevent bearing and wear-related failures when the engine is stressed for long pulls or repeated runs.

The speaker is describing fueling strategy: adding as much fuel as possible to chase maximum power. In diesel tuning, too much fuel without the right supporting changes (like timing and nitrous calibration) can lead to incomplete combustion, excessive heat, and catastrophic failures.

“Dinopole” appears to be a slang term for a dyno result/pull that’s strong enough to look dominant. In this context, it means the dyno run looked effortless because the tuning (especially timing) matched the nitrous level.

In racing circles, “holding secrets” refers to keeping performance know-how—like tuning approaches, setup details, or component choices—private rather than sharing it openly. The host contrasts that with a community that shares information to help everyone improve.

“3000 horsepower” is a benchmark number in high-output racing and drag-style builds. The host is pointing out how, historically, reaching that level was considered unrealistic, but newer development and testing have made it achievable.

“Slip” in an automatic-style transmission usually means the clutches aren’t fully locking, so the transmission can’t transfer power efficiently. That can show up as heat, delayed response, or reduced acceleration because the drivetrain is losing torque while the clutches slip.

A “dyno strategy” is the plan for how you run the car on a dynamometer to safely evaluate power and drivability. Here, the host is describing a setup that depends on the transmission behavior—specifically whether it slips—so the test results match real-world data.

Matching “RPM on the dyno” to “RPM on the data log” means the engine speed trace from the dyno test aligns with the recorded driving/track data. That alignment helps validate that the dyno run is replicating the same operating conditions, so tuning conclusions are more trustworthy.

A “clutch pack” is a stack of friction plates and steels inside an automatic transmission that engages a gear. If each clutch pack holds the commanded behavior, it suggests the transmission is locking up correctly and not slipping under load.

“47/48 style trans” refers to a specific transmission family used in diesel performance builds, commonly discussed by model number. The key point is that they’re using a known transmission design as the base, then modifying it to handle the power without slipping.

“Aggressor 480s” are specific turbocharger units (a model/size designation) used on the manifold. In drag diesel builds, turbo size strongly affects spool characteristics and how much boost the engine can sustain across the run.

The Dodge Charger is a full-size American muscle sedan/coupe that’s commonly discussed in performance circles because of its strong aftermarket support and wide range of engine and drivetrain setups. In a diesel-performance context, it may come up when people talk about building or tuning a platform that can be made to produce more power and torque. The “base charger” mention suggests the podcast is referencing a specific, smaller or earlier configuration as a starting point for performance work.

“FIS 50 mil gates” are turbo wastegate/blow-off style control components (gates) used to manage boost pressure. Using multiple 50 mm gates—two to atmosphere and one to the hot pipe—helps control how boost is regulated and where exhaust/pressure is routed during the run.

The “hot pipe” is the exhaust/charge piping area associated with the turbo system where hot gases or boosted flow are routed. Routing a gate to the hot pipe changes how pressure and exhaust energy are managed compared with venting to atmosphere.

“Pounds of boost” (transcribed here as “boots”) refers to boost pressure measured in psi. The speaker is stating the turbo system is producing roughly 90 psi of boost at launch, which correlates with the engine’s ability to make high power.

“1500 horse” is shorthand for 1500 horsepower, a measure of engine output power. In diesel drag racing, this number is typically the result of the whole system working together—turbo sizing, boost control, fueling, and supporting hardware.

“Gates went wide open” describes a control system that rapidly opens multiple flow paths or valves to deliver more air/fuel/boost at full throttle. On performance diesel setups, this kind of staged opening is often used to manage spool/response and keep the engine in the right operating window.

“Pounds of boots” is a slangy way to talk about the boost/pressure level the setup is producing while using those intercooler boots. In drag racing, maintaining a target pressure under load is crucial for consistent power and repeatable times.

“Intercooler boots” are flexible couplers (often rubber or silicone) that connect the intercooler to the intake piping. They help seal the charge-air plumbing and tolerate vibration/heat expansion, which matters on high-boost setups where leaks or poor fitment can hurt power.

V-bands are high-clamp, quick-release style exhaust or charge-pipe clamps shaped like a “V” that lock together with a single band. They’re popular in performance builds because they seal reliably under heat and pressure and are easier to service than traditional hose clamps.

“12 valves” refers to the engine’s valvetrain configuration—how many intake/exhaust valves are used per engine cycle. In performance diesel discussions, valve count often comes up because it affects airflow potential and how the engine breathes at high boost.

“Eighth mile times” are drag-race elapsed times measured over an eighth-mile (0.125 mile) distance, commonly used in some diesel/drag communities. Shorter than a quarter-mile, it emphasizes launch and early acceleration.

PSI is a pressure unit (pounds per square inch). In diesel performance circles, people often talk about targeting very high boost/charging pressure, where “100 PSI” implies extreme airflow and fuel delivery demands on the engine and turbo system.

A “rule change” in racing usually happens when a competitor’s approach exposes a loophole or creates an unexpected performance advantage. Organizers may tighten the rules or adjust categories to keep competition fair.

“Body on chassis” describes a vehicle architecture where the body mounts to a separate frame (chassis). This is common in many trucks and off-road platforms because the frame can handle loads and modifications more easily than a fully integrated unibody.

“Drive shafts” (driveshafts) transmit torque from the transmission to the differential(s). When a truck is built or modified, driveshaft length, angles, and balance must be correct to avoid vibration and to keep the drivetrain working smoothly.

“Chassis fitment” means checking whether a chassis (or chassis components) physically fits the vehicle correctly—alignment, clearances, and mounting points. In practice, it’s about making sure the parts land where they’re supposed to so the truck can be assembled safely and correctly.

“Dyno trim” refers to configuring the truck specifically for a dynamometer (dyno) session. That often includes swapping in the setup needed for testing—things like airflow, fueling, cooling, and any temporary hardware—so the vehicle can be measured consistently.

A tow rig is a dedicated vehicle used to transport a race car or sled-pulling setup to events. In this context, the “random boots” are sold through a power-driven tow rig setup, implying a purpose-built towing/transport system for diesel performance competition.

“Frame up” is shorthand for building something from the ground up on a frame or chassis. In this context, it means they fabricated the structure specifically for sled pulling, rather than modifying an existing setup.

Water injection is a diesel performance trick where a water (often mixed with alcohol) spray is injected into the intake to reduce combustion temperatures. Cooler combustion helps prevent overheating and can allow more aggressive fueling/tuning without the engine getting too hot.

“Peak at 1750” is describing where the setup makes its strongest pull—around 1750 rpm. In diesel tuning, the goal is often to shape torque delivery so the truck makes usable power at the rpm range where the event load is hardest.

Here, “spray” refers to the water-injection spray quantity/mixture being delivered into the intake. The speaker notes that the wrong spray combination can raise temperatures, implying that injection timing/amount must be tuned to avoid overheating.

The “head” here means the cylinder head, the component that houses the valves and combustion chambers. In high-power diesel builds, cylinder-head design and valve durability are critical because they determine how well the engine tolerates heat and pressure under heavy fueling.
