Quick question for you guys with supercharged 4.6 3v, what is your fuel rail psi under boost? At idle and normal driving, my gauge is reading right around 40 psi, under boost it spikes up to at least 67 psi. I am trying to trouble shoot a slight hesitation/bogging condition I am getting from time to time. I have cleaned the maf and throttle body, cleaned the air filter, installed new plugs, fuel filter was changed last year. Fuel pump is stock with 60k miles, thinking the filter sock might need to be cleaned or replaced. Currently running an off-road x, and upstream O2’s have been replaced in the last 5 years, and car is throwing no codes.
