Which CLA engine gains most?
The 2.0T petrol turbo shows the largest gains in outright figures, while the CDI diesels excel at usable mid-range torque.
Do you do pop and bang on this model?
Yes, with 37 files it is one of the more requested on the CLA. Note it can affect exhaust components and is not intended for road use.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
