Ok, I checked out the turbo pics and see that the CBV and wastegate are not the same thing. Also read up on them a bit, but maybe I'm dense.
Seems like the wastegate is a bypass that limits the amount of max boost by opening at X psi. The CBV vents pressurized intake air from the compressor output back into the compressor intake and only really exists to take strain off the compressors.

So then the only thing that could be causing this is the wastegate not operating.
I saw the CBV moving today when I revved the engine.
I'm gonna get up early and check the turbo->wastegate hose. I bet (and hope) that's it.
