hitting fuel cut

0Ok so my FD was rebuilt recently and is now broken in, I have been driving it and had it (what I believe) hit fuel cut. I turned on my pfc's peak hold feature turned on and from what I gathered it hit a peak boost of .74 which is about 10#'s and nothing happened worked great. Then the other night I decided to give it a second gear run and almost instantly it stopped(fuel cut?) I checked my pfc's peak boost and it was .83 that is only thing that is different. So I am guessing that it is beyond what the pfc can control? I was hoping if this is the problem will a boost controller fix this? Any input or links would be great, thanks!

Mods: intake, dp, res mp, racing beat catback, greddy smic, pfc, street port and a pfc. My waste gates are also ported. I may be forgetting something but that is pretty much it. Thanks again!

Fuel cut with the PFC occurs at .2Kg/Ccm^2 above your set PFC boost value, even if using an external EBC.

I understand what your saying car is going to be tuned as soon as the injectors get here that ordered a week ago. I am not ripping on the car, this occurred at about 3500 rpm's. My goal of this thread is so when it goes in to be tuned that it is "ready" meaning I dont need anything else to get it tuned.
