Why your ECU is safe with us
A remap is only as good as the file, the tools and the care behind it. Here's what comes with every ECU tune.
Custom tuning file
Written for your exact car and engine by Top Gear Tuning. We're a verified dealer.
Professional tuning tool
We read and write your ECU with the Alientech KESS3, a professional-grade programming tool.
ECU-protected power
A mains-powered battery support unit keeps your car's voltage steady while we work on it, so a weak battery can't interrupt the tune.
Health check before & after
We scan for faults and check live engine data before we tune, then again after. You know the car's healthy both times.
Lifetime software warranty
For as long as you own the car, if our tune causes a software issue, we'll fix or reinstall it free.
Terms & conditions apply.
