SMGII shifts faster than a non-SMG, and that it was designed specifically for track use and has been shown in the hands of skilled drivers to produce faster lap times. Get some track days with training under your belt, that will shave many seconds off your lap times. Tuning your ride is best left until after you've tuned your skills.
