Running a hydraulic actuated injector in the Powerstroke is somewhat like controlling spark timing on a gas engine with a rubber band. It works OK at slower engine speeds but up at higher engine rpm's the fuel cycle beginning point/cutoff point is giving everybody performance headaches to say the least. The 6.0 injectors had better performance electronics but still dosen't control precise fuel delivery like the common rail system.
That's the main reason we don't see exorbitant HP numbers with the 7.3's. Than we try to make up for injector downfalls by using excessive drugs and stuff busts.
I've used the "hand basket" myself picking up parts.
IMO, Cummins ain't the answer. Common rail is..
