What to Expect
- 01 —
Assess
We review the vehicle, engine setup, ECU, fuel, mods, and intended use before touching anything.
- 02 —
Inspect
Mechanical condition, wiring, sensors, and support systems get checked first. A tune can't fix a hardware problem.
- 03 —
Tune
We work through startup, idle, load, cruise, part throttle, fuel, ignition, boost, and wide-open throttle (WOT) — in order.
- 04 —
Verify
Data is reviewed throughout. Final checks confirm clean, repeatable, predictable performance under changing conditions.
With remote tuning, it's the same standard — just a different method.
