the best way other than the last listed extreme nitrous, and the listed tune up the best way could be here:

however, for that price, you may just want to sell your current A4 and move up to a newer model, the S4, or the TT. I too looked into this, but with the cost plus installation, it wouldn',t be any better. add that to possible tranny problems with the added muscle, it',s not really worth in I believe.
