here's pic of friend scat pack 392 w/shaker. the 392 is 485hp & is fast. assuming yours like min dp's & 4+ liv tune, it should get you if it an a8, that a8 is as good if not better than the a6, because it's hooked to launch control set by driver, now if it's a manual odds increase a lot. cars weigh very close & our awd helps some but not enough. that launch control is one fancy nanny. now if it was a 345 rt like mine w a tune, sho would win. their tune does not due anything close to our tune & dp really help low end torque.
