I just moved to Colorado, and currently drive an 05 BMW 545I. I don't like the idea of cruising up to Breckenridge in this RWD Beast. I am just about to pull the trigger on an 02 S4 Avant, but can only find an automatic. I will not buy the car unless I can get a Turbo upgrade, and chip that will put the HP above the 415 range. After searching on line, I have only found kits for manuals. Is there a kit for the auto tranny.

 

That's a lot of hp for the triptronic tranny. I wouln't want to risk it considering a new tranny is VERY expensive. Welcome to the forum btw.
