I have a 07 C6 A6 with Corsa Sport catback VR intake w/TB spacer. I used the Diablo Tune and my question is, with a tune should my car run Leaner? Before my tune my tips were on the brownish tan color (lean) now they are Black and sooty (rich). Is this normal?
Thank You

Should run leaner. Don't go by the soot on the pipes. I get some on my Bullets, too. Corvette Forum has a discussion on this.

lol, I think it's his discussion on the Corvette forum...

Like Whiterock1 says though, don't go by the soot on the tailpipes, the car is definitely running leaner than stock.

Thanks
