The voice of reason responds!!!

Thanks Dave, you just really did not help me figure out whats next

Just kidding. 38r or pump next?

I am leaning towards pump because I can feel the truck fall flat on its face when I floor it for a long acceleration and it gets around 2700 rpm...

If I am at 2600 and floor it, it will scoot for a bit. Does this mean its running out of oil to push fuel or am I just imagining things and running out of usable rpms?

Pretty much the nature of the beast. You are running out of usable time to inject fuel (slow stock injectors), HPOP is about out of steam, and turbo has nothing left in it.

IMHO if you are seriously considering upgrading injector's to singles, the turbo would be a better upgrade as the singles require less oil than the stock splits will.

FWIW after I blew a HPOP line with my 238/100, I put a stock 17* in place of my twin Stealths and could not really tell the difference. But with stock injectors the Stealths made a very noticeable difference, engine just felt way smoother and pulled a bit harder up top.

Have you done any testing on your HPOP to see how healthy it is?

It is probably safe to say that the HPOP is not too bad then.

Do you have access to a scanner that can view the ICP PID?
