Only way to fine out would be do a 1/4mile power run on the dyno and watch the shift points, as all the dv is doing is making the shift much crisper, the oem N valve is good for a 300+bhp power run and will give the same results as the 007p, but the 007p is much better in the lift off shift area.
I will order one tomorrow and play with it on a few customers car.
