The mack plug gives you another ?2?mm of travel, while the plate limits max rack travel, so the mack plug is pointless if you're limiting travel elsewhere. I say take the plate out and sell it on cummins forum for an ungodly amount of money. Unless you are super heavily over fueled and actually need to limit your WOT fuel. Thats my perspective though LOL
Well, I appreciate the info, I think I have plenty of air so I'll give it a whirl on pulling the plate. I will say this, when I had my pump worked on, I was sitting on a worn out engine and hx35. Not making excuses though, I never once thought about how both can contradict each other. Or at least the plate...lol
I will Dyno again 5th of Oct . Texas Mobile Dyno, was told it was a Dyno jet.
