Three Diesel Tuning Levels

Pick the Level. We Build the Order.

Power upgrades fail when parts get bolted on out of sequence. These are the three levels we build, each one complete at its stage.

Level 1

Tune and Breathe

The honest gains your stock hardware supports.

Diesel tuning matched to your hardware
Intake and exhaust flow improvements
Gauges and monitoring so you can see the engine
Transmission tuning to handle the added torque
Baseline health check before any power is added

Level 2

Fuel and Boost

The middle build most trucks actually want.

Injector and lift pump upgrades sized with headroom
Turbo upgrade or drop-in improvement
Head studs and supporting hardware where the platform needs them
Cooling upgrades for West Texas summers
Tuning revised to the new hardware, verified under load

Level 3

Built Engine Territory

Past the stock ceiling. Time to build the bottom end.

Power targets beyond what stock internals hold
Full performance engine build, in-house by Chris and his team
Drivetrain built to match the new number
Fuel system engineered as a system, not a parts list
Quoted as a complete build, no surprise phases

How It Works

Health First. Power Second. Proof Third.

Adding power to a tired engine buys you a tow bill. The order below is not negotiable, and it is why our upgrades last.

01

Baseline the Truck

Compression health, fuel system condition, boost and EGT numbers as it sits. The truck earns the upgrade first, and you get an itemized quote for the level you pick. If the baseline turns up a fault, we sort the diesel repair before we sell you power.
02

Build in Order

Supporting parts go in before the power that needs them: fuel before boost, studs before cylinder pressure, cooling before towing season. OEM or proven parts only.
03

Verify the Result

Boost, fuel pressure, and EGTs watched under real load, tune adjusted to the hardware, and the truck test-driven by Chris before release.

Standards and Capability

The Platform Sets the Rules. We Just Read Them.

Every diesel platform has known weak points, and pretending otherwise sells parts but breaks trucks. Our job as a diesel tuning shop is matching your goal to what the hardware actually tolerates.

Platform Knowledge Power Stroke, Duramax, and Cummins limits known cold: head gasket ceilings, stock turbo walls, injector windows, and transmission tolerances.
Emissions Compliance Street trucks stay legal. We build power within compliant tuning and hardware, and we say no to delete requests on registered vehicles.
Work Trucks Welcome Towing and hot-shot builds are a specialty: more power that survives loaded miles, not dyno-queen tunes that melt under a trailer. Fleet accounts are handled the same way.
One Shop Accountability Tune, hardware, and transmission work all handled here. When one shop owns the whole combination, nothing falls between vendors.

Diesel Tuning FAQ

Common Questions

How much power can I add with just a tune?

It depends on the platform and the truck’s health, which is why we baseline first. A tune alone gives honest gains on most stock diesels, but the bigger jumps need fuel, boost, and hardware behind them. We quote the real path to your number instead of overpromising a flash.

Do you write custom diesel tuning or load off-the-shelf files?

Tuning is matched to your actual hardware, not flashed from a shelf and handed back. The file follows the parts, so it gets revised as fuel, boost, and cooling change through the build, then verified under load before you take the truck. That is the difference between a tune that lasts and one that runs out of headroom in a month.

Will a tune hurt my engine or transmission?

A conservative tune on a healthy truck, no. An aggressive tune on tired hardware or a stock transmission, absolutely. That is why the baseline check and transmission tuning are part of the job here, and why we stage power behind the supporting parts instead of ahead of them.

Do you delete emissions equipment?

Not on street-driven, registered vehicles. We build power within compliant tuning and hardware, and there is plenty of it to be had. It protects your warranty position, your resale, and your liability, and it is the only way we will do the work.

Can you upgrade my truck for towing instead of speed?

Yes, and towing builds are some of our favorite work. More usable torque, lower EGTs, better cooling, and a transmission that holds it, built for loaded miles across West Texas. Tell us the trailer weight and the routes, and we will build for that reality.

What does diesel tuning cost in Midland, TX?

It scales with the level: a tune-and-breathe package, a fuel-and-boost build, and built-engine territory are very different investments. After the baseline check you get an itemized quote for the level you choose. Call (432) 557-6500 with the truck and the goal.
