IP adjusting
I've got a '94 F-350 7.3L Factory Turbo Crew Cab Duallie. It has 86,000 on it. It's seems to be all original. I have had to replace the injector seals and glow plugs. My problem is that it smokes. On the highway at 60mph if I give it 3/4 throttle it smokes black, even when rolling down South Grand here in St.Louis at 30mph, if I bring it up off idle it will produce a puff of black smoke.
As I see it black smoke is a waste of fuel($$$) I would like to keep up the power but would also like to get some kind of better fuel mileage. I get roughly 13mpg if I stay under 60mph and anything over the best I can get is 10mpg. i think this truck has low gears also.
I have ran into the previous owners son and he said his dad turned up the injection pump(to hang with his friends with powerstrokes) and then promptly blew the tranny out. The son said his dad never turned the pump back down though. His dad just spent over $5000 to rebuild the tranny to handle the engine.
Anyone here in Saint Louis know of a good diesel mechanic to set my pump?

OK, here's what I found out...eek. Good luck 
"Ok, the information I have says there is NO way to turn up the pump. The stanadyne pumps werent very friendly to modders. They have higher flow injectors, but not much else. He may have injector issues or pump issues with the excessive smoke and fuel use. The manufacturer I spoke to in california said if you turn them up, they last about ten minutes, then self destruct. He's going to spend sizable amounts of money to change it either way."
