Fuel pressure issue is fixed. I moved the pump to the back and under the tank and replumbed my feed line. Pressure now builds and holds under boost and AFRs are more on target.
The Walbro 392 didn't have this issue 'cause it can suck a golf ball thru a garden hose but this AEM is a different animal apparently. I need to square away a few things and will start tuning and increasing boost. Shooting for 10psi with safe AFRs. Thanks again for all the suggestions guys!
