You will need the BFX scan tool if you don't already.
Measure ICP and IPR % at wide open throttle. Next, try buzz testing the truck cold. if you have a weak injector it should show it self. Next could be low fuel pressure or a form of blockage in the tank. the list can go on if you don't have the proper tools
In all reality having a true scan tool, AutoEnginuity, or forscan is the most help full tool when diagnosing anything. I'm sure Ralph has told me at least 10 times that i need 1 of those 3....
the shot in the dark answer is just replacing the CPS with a FORD one and seeing what happens
