Diesel Performance Upgrades in Cheyenne, Wyoming
Honesty & Quality
Performance work at TDC isn't about dyno-queen numbers — it's about building trucks that tow harder, run cooler, last longer and get out of their own way. Turbos, injectors, fuel systems, intakes, transmission upgrades and the supporting hardware to make it all live together: planned as a package, not bolted on piecemeal.
Trevor builds around how you actually use the truck. A ranch truck that tows a stock trailer weekly needs different parts than a daily driver that wants some attitude. And because reliability upgrades like grid heater deletes and disaster prevention kits live on the same menu, the builds here are ones you can depend on when it's 20 below and the trailer's loaded.
Upgrades Services
Performance Turbos
The right turbo transforms a diesel — quicker spool, cooler exhaust temperatures on a grade, and real power without the smoke show.
Learn more →Performance Diesel Injectors
Injectors are where diesel power actually comes from — more fuel, delivered cleanly, makes more torque.
Learn more →Cylinder Head Upgrades
The cylinder head decides how well an engine breathes, and on a built diesel it's also the component clamping combustion pressures the factory never planned for.
Learn more →Custom One-Piece Driveshafts
Factory two-piece driveshafts carry a built-in wear item — the carrier bearing — and on lifted, long-bed, or hard-working trucks, it fails again and again, bringing vibration back every couple of years.
Learn more →FASS Fuel Systems
A FASS system is a frame-mounted lift pump with serious filtration and air/water separation — and on modern common-rail diesels it's one of the best reliability investments available.
Learn more →Upgraded Intakes
A turbo diesel making real power needs airflow the restrictive factory intake tract wasn't designed to deliver — an upgraded intake feeds the turbo more air, drops intake restriction, and adds a little turbo note in the bargain.
Learn more →Grid Heater Delete Kits
The 6.7 Cummins has a known time bomb: the grid heater's electrical nut can fatigue, break off, and drop straight into the intake — where the engine ingests it and destroys pistons, valves and heads.
Learn more →Suspension Leveling Kits
Trucks leave the factory with a nose-down rake — there to accommodate payload, but it looks like a lot of wasted tire clearance up front.
Learn more →Turbo Piping Kits
Factory plastic intercooler pipes and stock boots are engineered for stock boost — start turning up a diesel and they split, blow off, and leave you limping on the shoulder with a truck that sounds like a shop-vac.
Learn more →Heavy-Duty Steering Upgrades
Big tires, a leveled or lifted stance, and heavy front axles expose the factory steering linkage for what it is: adequate for stock, marginal for more.

- Start with the mission
Towing, daily driving, or fun — the truck's real job decides the parts list.
- Check the foundation
Compression, fuel system health and transmission condition get assessed before power gets added on top.
- Build as a system
Turbo, fuel, airflow, tuning and transmission have to match. Mismatched parts make heat, smoke and broken trucks.
- Support it after
The same shop that built it maintains it — no finger-pointing between the tuner and the mechanic.
