I have an A4 with 3.23's in it now. Looking at 3.73's and I am guessing I want a full install kit with bearings shims and everything. What is the best brand and the cheapest place to get them? Also if you know do the mail order tune guys like pcm4less do they tune for gear changes as well?

 

as for the first question...i havent the first clue, im in the same position and was about to ask the same question. But yes PCMforless and MadZ28 do tune for that sort of thing so you can get the most out of them.

 

Ive heard good things about motive, thats what i am looking into getting.
