I'm sure there's a few hp to be gained by a bigger throttle body, but I have plenty of peak hp. What I want is driveability. With a large TB, small throttle movements make large flow changes making throttle control more difficult which can lead to jerkiness and wheelspin.

I imagine you'd be fine with a 70 or 75mm TB, but I'll stick with my stock Carrera TB.
