I can bet that the pump swap will make no difference. What do I do after I change it? After this part being changed wouldn't the only factor left be the tune? I have been thinking about sending the injectors out for testing but I have already tested them for leaks. I could also force the lpfp to make 90 psi and have all the plugs out and check each one again if the initial test wasn't "good enough". At what point can I throw this back on LMS?
