I believe you're maxing out your MAF so it's telling the ECU to go into fuel cut. You will need to clamp the MAF signal so the ECU doesn't see all the air actually coming in.

The F/IC isn't used all that often on our cars.. it just doesn't seem to work that well. There's a guy that made a thread in this same section about getting it to work, and I think I recall him using a MAF clamp or something of the sort. Lemme see if I can find it.

EDIT: Ok, here it is.

That should help you if you choose to continue down the F/IC road, but many of us will suggest using the Split Second Air/Fuel Calibrator (SS AFC v2) instead. It's much easier to install & tune, and it has been proven to work wonders on our cars. Good for up to 16 psi.
