WE DON'T
GUESS.
WE CALIBRATE.
Tune files, tuning hardware and hands-on diesel repair out of Lafayette, Indiana. Half-ton work trucks to X15s to sled pull engines that don't know how to lose. And when somebody else bricks your ECM — we bring it back.

Emissions-compliant tuning
100% compliant calibrations for on-highway trucks & equipment
Every emissions component stays on the truck and stays working. We calibrate around the aftertreatment instead of deleting it — better drivability, cooler EGTs and fewer regens.
Competition side
And a race program that stays on the track
Sled pull and drag calibrations are a separate line, sold for off-road and sanctioned competition use only. Two different jobs, two different files — we never blur them together.
FILES ON THE SHELF
Bought online, built by hand. Every file is checked against your VIN, hardware and how the truck actually gets used.

BRICKED ECM? WE BRING IT BACK.
Failed flash. Dropped connection. A “tuner” who ran off with your money. We recover Cummins CM2xxx, CM8xx and Cat A4/ADEM controllers on the bench — no dealer, no core charge, no new module.
01
Tell us what happened
Send the engine, module part number and how it died. We answer with a shipping label.

Direct-to-module bench flash. VIN, parameters and trip data stay where they belong.

Back on the truck
Tested, packed and returned. Bolt it on, key it up, go to work.

IN THE SHOP
Basic service through full competition builds. If you need a work truck that never lets you down, we'll build it. If you need an engine that wins, we'll build that instead.
