unplug the MAF and see what it does, don’t think that’s your issue, most likely the FPR or lift pump, play with the pressure on it.

Factory filter housing is deleted. Fass pressure at 8psi.
So the truck runs smooth and no haze or smoke with MAF reading below 38-40.
But with the MAF reading 38-40 it reads low at WOT 350-375. Any ideas why it would reads low at wot? New air filter dry air filter (not oiled) new MAF SENSOR, and all connections are tight
