A multitude of problems..
Last year I changed (all at one time) the following parts:
Turbo- 38R
uppipes
Non Epbv pedastal
glow plugs/relay
UVC harnesses
Injectors-Reman single shots
Regulated return.
IPR
After a year of driving I'm having a problem that is progressively getting worse. On cold start, HPOP pressure 400-600 psi(I have a guage) however once the oil temp comes up it will barely idle in stock tune and I must switch to either my tow tune or 80E to make it idle. On top of that it just has no power off idle. With an empty truck I must give it a little fuel when I release the clutch something I never had to do even on a hill with the stock set up. The other problem I have is high EGT when towing on hills. I'm thinking I have injector o ring issues or maybe a bad injector itself. I do not have AE(funding issues at the moment) but is there any other way to isolate what the problem could be? Thanks in advance!

Can I ask what is a good ICP and when can it be considered low? Thanks.

Long story, but: Weak HPOP can do this, tune can do this, UVCH can do this, ICP or IPR can do this, or it could just be a "stale" code. Have you cleared the old codes and started fresh?

Thanks for responding...No...I literally took it out of the envelope, had some trouble loading it on my daughters netbook(had to charge the battery of said netbook). I will have more time to mess with in the am. I replaced the UVCH and gaskets with new IH units. Does the 50 cent mod still have to be done with the new stuff?

I was driving the other day, engine not fully warmed up, and every time I would add throttle the SES would light. This happened a few times and eventually it started running that total crap. Looked down saw that my F5 display was blank, I was running on the stock tune at the point. Found a safe spot to pull over, shut the truck off and restarted and all was well from there on. Pulled the trigger that day on the AE.

You can always run a fresh buzz, KOEO, KOER, and data-log a short drive. You want to have a baseline, so if something happens... you have this information to compare with.

Nope, you're good. With your other answers, we're not going to catch what happened the other day because of the backlog of old codes. You'll need to clear all the codes (using the procedure I set up in the AE class [LINK]), then if that little bugger shows up again... you own his ***.

Cleared the codes this am. Performed buzz test on cold engine. No faults found. Started truck, idle smoother, seems to run better. All good, no return of codes except for the EBP ones. However, it is still doing the original problem.
