Frequently asked questions
Frequently asked questions
Answers to the questions we're asked most often.
Is remapping reversible?
Yes. The original file is always backed up before any work, allowing a return to factory state at any time.
How long does the work take?
A Stage 1 remapping is generally done within the day. More advanced builds (Stage 2/3, options) take longer; the exact time is confirmed when booking.
Which vehicles are supported?
Petrol, diesel and hybrid, most European and Asian brands. Send us your model and its engine for a precise answer.
Is remapping safe for my engine?
Our files are calibrated and validated by logs, within the mechanical reliability limits. We always favour a healthy gain over a maximum figure at the expense of longevity.
Are the 'off' options (EGR, DPF, CAT, AdBlue) road-legal?
No. These modifications are reserved for track / export use only and are not road-legal in Switzerland.
