How does this differ from the Mégane 3 RS entry?
Our history records the model under both designations. Each group covers different units, so it is worth checking both.
How much does the 2.0 Turbo take?
It is a turbocharged petrol with genuine headroom, which is why it is such a popular tuning base. Stage 1 works with standard hardware.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
