No my car is not stock. I have a 3:15 rear diff and a dinan software upgrade. The car is a high 14 sec car but my intake was screwing up at the track (little ghetto thing I had on there because I didn't have time to put the stock airbox in) and it needed inspection II, which it now has. I just bought a bunch of dinan stuff as well as UUC pullies. It will be a mid 14 sec car which is good enough for me because I don't want to spend 8g's on a s/c.
I can handle a 328 any day of the week no problems.........however I have yet to race one with more then just intake and exhaust.
