ODD BASE BOOST... could I be leaning out???

Hey guys,
I've been battling the intermittent base boost on my car, which will sometimes produce base boost up until 4000-4500 RPM, when it goes back to full boost til redline. I've come to a few conclusions, mainly that I believe that APC is working, and that when I get base boost, I am leaning out and knocking.
So, what does this mean? Could this be my fuel pump, not providing adequate fuel SOMETIMES until a certain high rpm, at which time it decides to work correctly? Or would this be the ecu, or some electrical issue?
I'm fairly certain that APC is working correctly, I've switched out the AMM, etc.
Please help me out if you can, guys. I really appreciate it!
