it seems your wastegates aren't getting any signal at all. check the source for the valve body. it may not have enough of a signal to do anything at all.

the NC side needs to be open. its where the pressure is being bled off so that your boost rises.

I believe the problem is that the avcr pressure sensor isn't reading the boost correctly.. I believe the way McKinney hooked it up, it is too far from a direct vacuum line..

I'm going to retap it today directly to the intake manifold and see if it fixes everything...

As for now my autometer boost gauge reads correctly and my AVC-r reads way off the way...

It's not even close to accurate... I think that's the problem..

Thanks!

thats also a possibility. the pressure source should be off of your FPR or something close to the throttle body.
