After installing a brand new throttle module and doing a software upgrade that is supposed to cure hesitation when accelerating (if I remember its aimed at the transmission) the car is still not up to par.

When I drop the hammer I still feel a strong inital kick and after less than a second the car goes flat for a second or two and then it starts to pick up. Any accounts of the car overboosting and the computer cutting the boost to lower it?

I miss the times when the car was responsive and would just haul ass out of the hole.

Thanks!
