90mm Vett/gto Throttle Body
If any of you with the 05/06's are thinking about swapping out the 85mm stock tb with the 90mm vett tb, you may want to hold off. Joe and i have run into a problem. The 90mm will not open 100%. It's only opening around 80% even tho the HP tuners scan shows 100%. This may not be a big deal, the 90mm(@80%) may flow the same as the stock @ 100%. auto Trans function should not be effected because the VCM is still showing full 100% at wot. will post more info as available.
