The secret to better throttle response lies in the WUR. Look into a vacuum sensing WUR (Rice Fueler). This instantly reduces control pressure with acceleration allowing the metering plate to move quicker. I did this electronically with my C2T with a frequency valve and a special controller I plumbed around the WUR and it made for a lot better throttle response.

If I ever get another C2T I will just put on the cat bypas, set the boost at .9bar, mod the WUR and put a set of C4 normal gears in place of 2-5.

This would make it a rocket ship.

by S2 do you mean 964 turbo S? do you mean 3,3 och 3,6?

do you have some pics and more info about your WUR fix that sound intresting
