Vic,
You are probably correct here. I bet that the throttle bodies really only open past half way, in the last part of the throttle pedal travel ?, therefore maximizing boost, and therefore torque ?. Dont get me wrong, there is still a lot of torque, with not a lot of throttle input, its just ive noticed, that if i want the mega performance, and that kick i keep banging on about, then you have to really ask for it, with full throttle.
