your plugs might be breaking up at high rpms if you are running 24+ psi boost. Check the gap and gap them back properly or if its fouled out, then replace it. I doubt it is fuel cut or boost leak.

You don't have your 3-port installed yet do you? Hahaha.

I would just drive it kinda easy until you get to CBRD.
