Have a new (2200 mi) '07 A6 and will be adding headers, hi flo cats and 160 deg stat next week. I think I will add a tune to make sure she doesn't run too lean w/ the new cats, etc. I'm still undecided about the CAI and am going slowly because I don't want any issues w/ the warranty. Does anyone out there have any suggestions or comments? What gains can I expect? Also, any recommendations for tuners (in the Tampa Bay area) are appreciated!
