Just a thought
anyone agree??

I agree that if you roll into the throttle the car feels OK. You just have to train yourself to do that.

As far as the slow revving, I think it's just that electronic delay between your foot going down, progressively increasing the throttle, and the computer reading the potentiometer. With SRM, the computer just sends a command signal that basically says "5,000 rpm NOW!" and the engine reacts. With the throttle, the computer is reading progressive throttle input from 0% to whatever amount of throttle you give, so the engine isn't going to rev quite as quickly.
