A4 (B7 Platform) DiscussionDiscussion forum for the B7 Audi A4 produced from 2005-2008.5
I just bought a used 2005.5 and I wanted to get some more power... I was thinking about going to apr stage 2 or 2+... I did a search on this forum but I can't find any solid #'s on the hp/tq increase either at the crank or wheel... Can anyone give me any idea of how much more I would gain over stock?
Also, what would be the fuel economy hit?
