Sounds like the pump is not putting out at higher rpms, or you have a way too big return pill in the injection.

thats what rons was asking me ...but the egt is reading fine and i change the valve out of my other toilet on my other car ..if it was stuck it would be to fat and the egt would show ..plus the oil would be shot
