do you have ## bov recirculated? if not that will cause a sudden rich mixture and cause ## car to kinda buck when letting off the gas.

nope its not recirc

There's your first problem. Do a boost leak test as well.

youre gonna have a little problem recirculating a TIAL bov . Theyre not meant to recirculate, and they dont make a recirc piece for it...unless you want to put a bag around your bov and have a tube routing from the bag into the recirc piece heh. The BOV is the problem. Also, like dream_on said, do a BLT.

Lack of BOV re-circulation, compounded by FPR overrun.

he has a fp. regulator though so what psi are you running
