Boost Cut!?

Ok, I have a 87 TII, and I have full racing beat exhaust, fcd, ACT Stage 2 clutch, and bov...... And when ever I boost it cuts out at 6k rmps in 2nd, and 5.5k rpms in 3rd gear.... This started happening a couple of days after the new clutch. Now I've checked my spark plugs, and ugraded my old fcd to an HKS fcd, and it still does it. Any suggestions, on why it is doing this? Could it be some other type of mechanical problem? Feedback would be highly appreciated.
