Angry SR20DET falls on its face @ 5.5K rpms

I've been working on my friends SR20 and I can't figure out why it's doing this. It's almost like it hits fuel cut, or a rev limiter, and just completely stops building boost, accelerating, etc.

There are no boost leaks, AFR's are good, etc.

His set up is:

S15 T28 Turbo at stock boost
Apex'i AVCR
Sard 550cc injectors
Z32 MAF

I have checked timing,ignition timing, i've tried turning the AVCR to "off," I've checked plug gaps, etc. I've tried all I can think of.

Also tried to completely remove the AVCR from the picture, by unplugging it, and routing the wastegate straight to the hotpipe, instead of the boost controller. Same issue.

Any thoughts?
