it bounces off the revlimiter but without having to mess with the gas peddle your reaction for shifting is better I guess. Everytime I have done it the shifts have been so fast you dont really bounce off the limiter, just as soon as you hit the clutch shift and let out. Takes like a half second to shift and you dont notice any pause in speed. Before when I would let off the gas I noticed a pause before the turbos would pick up speed again, this way they never slow down.
