Sounds like the OP is running one of RCD's advertised power combos. Not sure exactly what their "poor boy" fuel system consists of but I know it uses an AD 150 as a pusher to the stock HCFM. I would assume they put the larger pick up in the tank to feed the Airdog. There should also be a regulated return of some sort under the hood. Don't take this as gospel coming from me, but that's my understanding of it.
My advise to the OP would be to add a Raptor fuel pump to your fuel system. It is also made by pureflow tech, like the airdog. The AD 150 (provided you have the required fuel pickup tube installed) should provide plenty of gallon flow. I just think your stock fuel pump (HFCM) isn't keeping up with demand. If all else is good and done right, I think your stock HFCM is most likely your problem.
