I have had my b7 a4 for 6 months now and love it, great for long journeys which my old car was not very good on being a civic type r. My question is what needs to be done to turn my a4 from 140bhp to 170bhp like they come out factory, is it just mapping or different turbo etc? I have found being auto it lacks power sometimes so a bit more would be helpful.[URL=http://s259.photobucket.com/user/mc_1985/media/DSC_1566.jpg.html][/URL]
