Stage 1 stays inside what the standard turbo, injectors, clutch and cooling were built to take. The figures above are the calibration we run, not a maximum. The car is checked for stored faults before and after, and the original file is kept so it can go back on.

A manufacturer can decline a warranty claim on a part they can show was affected by the remap. We tell you plainly what that means for your car and your warranty position before anything is done.

A Stage 1 remap is around 2 hours, in a single visit. Add a dyno session and allow 4 to 5 hours. The original software is stored and can be restored on request.
