Draft for MMT Performance to approve before the new site goes live.

Figures

Power and torque figures for each engine are typical results on a healthy vehicle. Dyno curves drawn from them are indicative. A vehicle’s own figures come from a dyno session.

Insurance and warranty

A remap is a modification: tell your insurer. A manufacturer’s warranty may not cover parts the remap could affect; ask us before booking if your vehicle is under one.

Emissions and the road

Removing or disabling a DPF, EGR, catalytic converter or AdBlue system on a road vehicle is an MOT failure and against the law in the UK. We repair them; any software change to them is for competition and off-road use only.

Track use

Changes for track use (speed limiter, launch control, decats and similar) are your responsibility to use within the law.
