It would seem that most people are very happy with the RS4's standard 380bhp, for a while. The next obvious move is the re-mapped ECU (chipping) and the exhaust system. This will give depending on engine about 460bhp. /ubbthreads/images/graemlins/smile.gif Has anyone gone the whole hog and pushed it to over 500bhp. /ubbthreads/images/graemlins/groovy.gif Questions - is it worth it? is it going to be reliable in the long run? and can you feel the extra 40 - 50 bhp?
