Clamp the map sensor voltage at 4.25v. I think there is a boost cut defender. I am assuming that fuel cut comes on when the boost rises above 14.7 psi? Correct me if I am wrong.

Winnipegamn, you are correct in that the fuel is cut at 14.7 psi. Tyler, you need a Greddy Boost Cut Controller. They can be found on ebay for around $50-60 or on horsepowerfreaks.com for about $80.
