Cutout/bucking w/ boost after PFC Install

[Mastaflash]

after installing my power FC D-Jetro and driving there is an odd problem going on. when getting on it, and getting into boost - aproximatly 2-4 psi - the car cuts out and starts to buck like it hit a slow rev limiter. the car has never done this on the previous enthalpy ecu setup.

the map sensor is installed and pluged into the side of the ecu case, and the iat sensor is installed and wired into the propor wire, the egt wire as indicated by the pinout in the instructions. no other changes were made other than removing the maf plug and shortening those wires back.

any suggestions for something to try, or anyone who has had this happen please help me figure this out.

You should get a wideband hooked up and check out your fueling when this is happening.
