Why so many DPF and EGR files?
They are known points on this engine, particularly in short-trip urban use. Disabling them is not permitted on public roads, however.
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.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
