An ecu remap has the potential to provide gains for everyone – some cars are more highly strung from the factory and hence see fewer improvements, whilst others can see absolutely phenomenal gains from nothing more than correct tuning of the engine (upwards of 50 rwkw). In saying that, anyone who has added any performance upgrade parts to their engine should most certainly consider a remap in order to get the maximum gains from their added modifications, as well as to ensure safe and reliable operation by dialing in the engine to suit the new additions.
