/ FAQ

Everything you need to know.

Will remapping void my manufacturer warranty?+
A remap can affect powertrain warranty in some cases. Your original file is always stored, so you can go back to stock anytime before a dealer visit.
Is it safe for my engine?+
Yes — every calibration uses dyno-proven files with live safety-log checks (knock, lambda, EGT, boost). We never push beyond the safe limits of your hardware.
How much power will I actually gain?+
It depends on engine, fuel and hardware. Enter your reg above for a realistic Stage 1 estimate based on data from cars we've tuned.
Do I need to tell my insurance?+
Yes — any performance modification should be declared. Most insurers cover a Stage 1 remap with a small premium adjustment; we'll provide documentation for your policy.
How long does it take?+
A typical Stage 1 install takes 2–3 hours. We offer mobile install for most vehicles within our coverage area.
