Idk. Should it be active? I haven't messed with it.

Absolutely! power enrichment (aka PE) is used to richen the fuel mixture under heavy throttle to keep the cylinders cool and from blowing up. Typically your engine will target 14.7AFR (AKA stoich) but when PE kicks in which is typically throttle position dependant it will richen to whatever it is set at I would assume around 12.5 for your motor. Let me see if I can get a snap of the table.

That could be the problem all along! not enough fuel at WOT.
This table is what tells the truck to enter PE, I have mine set so that it only enters PE with near full throttle at lower RPM but as the RPM increases I want the truck to stay cool and prevent knock so it enters PE with just 35% TPS.
