Does anybody know for sure whether a Remap to an Ecu is likely to be altered or deleted during a service? I have heard a story about a remap being altered when the dealership applied some updates to the ecu. I have convinced my dad that he would see benefits to his fuel economy not to mention a rise in power/torque if he had a Evolution chips remap, but if there was a chance that this could be deleted the next time he had the car serviced then this would not be viable option. Can anybody offer any advice?
