Frequently Asked Questions
Is ECU remapping safe for my car?+
Yes. Our Stage 1 remaps stay within safe OEM tolerances for fuel, boost, and EGT. Every map is fully reversible to factory and backed by a lifetime software warranty.
Will remapping affect my warranty?+
Cars outside manufacturer warranty are unaffected. For cars under warranty, the map can be removed at any time before a dealer visit, leaving no trace.
How long does a remap take?+
Typical mobile remap takes 60–90 minutes at your home, office or workplace anywhere across West London.
Do I need to upgrade my hardware?+
No. Stage 1 runs safely on stock turbo, injectors and clutch. Stage 2 requires supporting modifications such as intake and exhaust.
What gains can I expect?+
Gains vary by engine and vehicle. We provide before/after dyno-style figures for your exact model.
Do I need to tell my insurer?+
Yes. Any ECU modification should be declared. We provide a written specification for your insurer.
Will it pass an MOT?+
Yes — a properly mapped car passes emissions and MOT testing without issue.
