FAQ

YOUR
QUESTIONS
ANSWERED

An informed driver is an empowered driver. Everything you need to know about ECU tuning.

ECU tuning (or remapping) modifies the software parameters that control your engine — fuel injection, ignition timing, boost pressure, and more. By optimising these values for your specific vehicle, we unlock power and efficiency that manufacturers leave on the table for regulatory and commercial reasons.
Absolutely — when done correctly. Our engineers stay well within the safe operating parameters of your engine. We don't push hardware beyond its design limits. Every map is road-tested and reliability-focused. Your engine's longevity is always our priority.
It depends on the tune. Our Economy Tune is specifically designed to improve MPG — many customers see 10–20% improvements. Our Performance Tune prioritises power, which may slightly increase consumption under hard driving. The Blend Tune gives you the best of both worlds.
Yes. We always save your original ECU file before any modification. You can revert to the factory map at any time — for a warranty service, MOT, or personal preference. It's completely reversible.
Stage 1 requires no hardware changes — it's designed for a completely stock car. Stage 2 requires at minimum an upgraded intake and exhaust. Stage 3 is for heavily modified builds with turbo, injector, and intercooler upgrades already in place.
ECU tuning itself is legal in the UK. However, you should inform your insurer of any modifications, as they may affect your premium or cover. Some emissions-related modifications (such as DPF/EGR work) must remain road-legal. We'll always guide you on what's permissible for your use case.
