Electric fuel pump.
I put a Holley Red pump on my truck and wow what a difference. Any of you all with a turbo I have to tell you this is a must have. I think this can fix alot of problems on these old IDI,s with turbos on them at least it did on mine. I just wanted to let anyone without one know they need to get one. I do realize alot of you already have this, I am just a late arrival!

The top end is off the hook and it pulls real hard all the way to the top. I have real strong response out of the engine and it just start like a brand new truck. The sound of the engine is so sweet, I just cant say enough good about it. It was a pain to install but well worth the effort!

I can get black smoke but in general no. If I want the truck to dump some black smoke I have to have it in a high gear and dog it down on the speed then when its dogged down I can floor it and get some smoke while it tries to build up some RPMs. Just normal driving I really dont notice any black smoke though! I need to install a new exhaust system and I think I may gian even more power. The question is how much more do I need and at what price. What RPM does yours pull strong up to? I wish I had an automatic if I get on mine I am shifting kind of fast!

I think the better set up is considered to be the 5 speed (mileage and simplicity). The 4.10's don't help either. I'm kind of wondering if my DPS pump is bad but I could have other problems as well. I get black smoke at all RPM's and more noticeable when the boost is low. I have new injectors but one could be bad. The engine can pull up to 3700 rpm and it feels like a gas engine. I just have to ignore all the smoke.
Have you done the ram air and gauges yet?

I have a new Isspro pyro with an old boost gauge. I really question the boost gauge though. The highest boost I have ever had was 6psi but the truck runs like a bat outa you know. I have a massive hi flow air cleaner but I have yet to figure out how to do a ram air set up. I ordered a brand new turbo pump from the company that sells them on e-bay and I got screwed, I know from experience you can get a jacked up new pump. What boost are you running? I would think there is some way to get your engine to burn up that extra fuel. How about timing?

So it actually makes LESS smoke after the electric pump?? I ask because mine is turbo, but it doesn't run very clean.

cranked up the wastegate to get about 9 psi, some recommended turning it up to 12psi (see other post). 6 psi is the factory setting so unless you modified the wastegate, that is all you are going to get. I've been messing with the timing for a while, even looked for a shop to do it but they are few and far between. I've been doing it by ear.

I have no wastegate but I can tell you mine has a fast smooth rythmic sound to it. I mean it is incredibly smooth and fast much more so than it used to be before I did all the work!
