I have an E46 M3 stock with a 6 speed tranny. My friend has a 2002 Old style S4 with 6 speed tranny as well. Hes not stock...he has a chip...GIAC X-Chip he says and full Neuspeed exhaust with downpipe. Anyways...we've raced a few times already...from a stop and also from a rolling start at various speeds....his car just woops mine everytime. Now....as for driver skill...we both compete in SCCA events and have taking racing school at Laguna Seca....we both are pretty skilled drivers. From a stand still...he just smokes me out of the hole and I have no chance in catching him...I thought the E46 M3 should be able to smoke those darn S4's??? What gives? He always beats me by 3-4 cars. And on the freeway...he always pulls on my from 60 -120 about 1-3 cars and stays that way till we shut it down at 130( thats the fastest we've done). Im disappointed that my car cannot beat his cuz we are pretty competitive towards eachother and now he has the bragging rights that he's got my M3 beat. NOW....what can I do to make my M3 faster???
