Fuel Pump Regulator?
I keep getting a fuel pump regulator CEL. Would this cause boost fluctuate?

Possibly, if there's a severe drop in fuel pressure im sure the ecm would lower the boost. But without seeing logs its just guesses.

Check the wiring at the connector going into your HPFP. The wiring harness that it is attached to pulls on it something serious. I ended up ty-rapping that harness to one of the AC line the hold it.
