whats he running for boost pressure in psi? he should not be boosting untill the engine is warm anyways. however. It doesn't sound like fuel cut to me... when i hit fuel cut its like hitting a brick wall BABAMMM for a second, check enging light comes on and goes out and it runs fine if i pull my foot out of it. It happens about 14+ psi. That sounds like bad wires, or air and or fuel filters? i may even think it could be a bad throttle position sensor or mass air flow sensor? any engene codes present?. its it just when its cold and it runs sweet when its warmed up? could be any number or combination of things but id guess its not fuel cut unless he is over 12-14 psi boost. whats he running for bpu's basic performance upgrades? any mods?
