Building a slant for torque

Hey Rug, what ever happened to ya? Don't see ya around on the forums like I used to.
Career change. Went to driving trucks. Had to go over the road for 15 months. Duster hasn't moved since 2009. I have a D350 CTD that sat since 2011 or so. It's back running sort of driving. It has a fueling problem. I am thinking it's the injector pump. I bought a used IP and a bunch of extra stuff from a '92. I have bigger injectors, bigger turbo, 4" exhaust, all waiting to go on it. I need to get the IP sorted out (I think) most people on line are guessing with these diesels. I did change the governor spring to a 3200rpm, and did a THD +40hp fuel pin.

I popped onto Moparts the other day. No help there in the truck forum.
