Hi guys after some technical advice. I have a mk6 gti and love it. It’s had a stage 1 and I’ve put scorpion exhaust on it. Runs sweet as most of the time. I was getting a 222 and 221 Ecu alarm. Replaced throttle body and accelerator pedal. Alarms have now gone. Most of the time runs sweet but sometimes looses a little bit of boost. My question is do they need to be calibrated/reset. Is there a trick to resetting. Excuse my ignorance for not knowing.
