Which DS3 engine gains most?
The 1.6 THP petrol turbo, which is also the engine in the sportier versions. It responds strongly to electronic work.
Is a remap worthwhile on a supermini?
Yes, precisely because the car is light. The relative gain in torque is very noticeable in everyday driving.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
