How do mods affect the ECU? E.g. Straight exhaust, water pump, air filter, higher psi turbo.
Simple Question: I want a aftermarket ECU. I'm told they dyno the car to match the fuel, would this be affected if I later upgrade the intake and exhaust? Or worse still, if I fit a higher boost turbocharger. Would it be not be better to fit an ECU after these changes or aren't they related?
