Before installing the tune one has to make sure the car is free of problems and quality fuel is used, as well as proper operation of the tune (outside temperature, boost settings, etc.) Thus not to blame it on the tune after the CEL's are thrown. Mind you there are lots of stock N54s with problems in the first place. So I think the tuner will help you faster then us throwing random ideas around and making it look like a tuner war at the end.
