well we've got a GTU with a turbo motor that is streetported and it has just been broken in. i have 720cc primarys and 1600cc 2ndaries. lateley ive been having problems with the ecu dumping way to much fuel at around 4500-5500 rpms. it kind of hiccups and sputters and wont go any higher than that. just yesterday i took the turbo out and got the wastgate ported and put it back in today. it got rid of the bad boost creep i was having (this is a stock turbo btw) and now boosts at 6psi (it was going up into the 13-14 range) but i have not been able to do anything about my fuel problem by playing around with the super AFC. i dont really have all that much experience with an afc, and it did not come with instructions. any advice or prior experiences would be appreciated!

thanks
