Hey.
I am planning to get a full TNT stainless exhaust for my 2002 330i and Uni Q chip. I've heard the ECU auto adjusts to a degree, should I first put the exhuast, and wait a little while for things to settle in before chipping or do I chip directly afterwards??
Will the engine run lean without chipping immediately afterwards?
Thanks
