Is a remap worthwhile on a supermini?
Yes, precisely because the starting figures are modest and the car is light. The relative gain in torque is very noticeable in everyday driving.
Do you cover the BlueHDi versions?
Yes, both the 1.5 and 1.6 BlueHDi are present in our catalogue alongside the older HDi engines.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
