my car had a fast 90 ttb from previos owner. it would stick just off idle so when I got the car tuend they said the stock ttb on the 02 ss is z06 and flows like 80mm which is fine for what I am doing. I have the stock motor with z06 intake and a sts turbo making 8.5 lbs of boost. Replaced the fast with the stock one and sent it back to fast they sent me a new one in the case (nice case to ship a part in) and I'm wondering what would be best to keep the stock one on? I am not planning on changing much more at this time want to save for new camaro. now if I happen to hurt the motor I would like to get a stroker forged to run 16 to 18 lbs but that's another issue altogether. Should I sell the fast or put it back on???
