500+ trucks tuned
"Gained 120hp and the truck pulls like a freight train. Best money I've spent on it. Tune came through same afternoon."
Tyler B.
2021 Ram 3500 — 6.7 Cummins
"Dialled in perfectly. Fuel economy went up, EGTs came down, and it pulls harder than it has any right to on a stock turbo."
Mike D.
2019 Silverado — L5P Duramax
"Ran through three other tuners before these guys. Night and day. No more surging, no more hot EGTs — just pulls clean."
Jesse K.
2018 F-350 — 6.7 Powerstroke
"Had the tune done same week I deleted it. Truck is a completely different animal. Consistent, reliable, pulls hard."
Cole M.
2020 Ram 2500 — 6.7 Cummins
"Fast turnaround and the tune is rock solid. No check engine lights, no issues. Just pulls hard every single time."
Ryan S.
2017 GMC Sierra — LML Duramax
"These guys know Powerstroke inside out. Threw everything at it — new injectors, bigger turbo — and the tune kept up."

2022 F-250 — 6.7 Powerstroke
