Ok, so I pulled the MAP hose off, it had a small split on the one end, I trimmed and put it back on, drove the truck home, no difference really, so I bought new hose and installed it still no difference, so I though I would restore it back to the original program just to make sure it wasn't anything with the Edge programmer, after I restored it to the original program it was really bad, the truck wouldn't hardly climb a hill on the road to my home. The engine was running around 3000 rpms and barely made it up the hill, the Turbo never did build any boost, based on that and what it felt like to me, I am thinking maybe the cat is the problem. I will try bypassing that tomorrow and let you know how it goes.
Again I appreciate all the help. Thanks!!!!!

 

Does the truck blow any smoke when it's low on power like that and you're hard on the throttle?

 

It was dark outside at that point, I was trying to see if it was smoking and it didn't
appear to be smoking.

Ok so tonight I unhooked the exhaust in front of the cat and test drove the truck. No improvements, I set it back to the original program and when driving up the hill the RPM's would go to 3200, I was going 30mph and no boost. I help it on the floor all the way up the hill and it stayed right there, no smoke at all. I then reprogrammed it and it would go as fast as I wanted it to go and build boost pressure up to 28 psi in about 3 seconds or less,it may have kept building psi but I had to get out of it. However when I throttled it hard it poured the smoke for just a second or 2 and cleared up. it acted the same with the exhaust unhooked in front of the cat and hooked up as normal.
Anyway I look forward to hearing your thoughts on what the next move should be.
Thanks for your help!!!

 

Pull it off and clean it like mike said in his first post. That way that can be resolved and we can move on from there or it might fix the problem. Ton of miles on that turbo. Goodluck

 

Ok so I pulled the Turbo off over the weekend, cleaned and polished it just like the instructions said to do. The truck seems better as far as the Turbo spooling up, however it is still not right. It is taking a while for it to spool up and still putting out some black smoke for just a few seconds before it really kicks in. I drove it to work today and it seemed to be working ok on the way in, then it was acting up again on the way home.
It is better than what it was before, just seems to be sluggish still when starting out.
What do you think I should do next?

 

Has the EGR valve been pulled and cleaned? I can't believe I didn't ask this in the first post.

 

No that I have not done. The truck seems to run ok after it is warmed up also. Is there an instruction on how to clean the EGR?

 

It's right on top of the intake manifold. Unplug the wire harness, two bolts hold the valve in, just remove it out of the intake manifold and clean it. Remove the o-rings off of it first, go at with carb cleaner (DO NOT use brake cleaner), a small pick and a toothbrush will probably help. Sometimes they're a pain to get out too, you may have to pry on it with a big screwdriver or the sorts.

 

Thanks Mike, I will clean that and let you know how it goes.
Thanks for all your help so far!!!

 

No problem, let us know how you make out. There are probably dozens of vids on youtube pertaining to the EGR valve if you need some visual aids too.

Here's a good article on the EGR function: DTS Articles - Diesel EGR

Here's one on cleaning: DTS Articles - EGR Servicing

Those should help!
