Over 100 psi at idle truck won't run long enough to drive test as well as won't get above 20mph without a downhill

Contribution test comes back normal, it'll run fine cold until I touch the throttle then lope/stumble for a few seconds to a minute before clearing up. VGT actuates manually turbo changes tone when upping the duty cycle. When driving it barks, pops and bucks. Lopes in gear after a slight amount...

List of replacements: -IPR -ICP and pigtail -EBP sensor within last year, little drive time since. -New alternator and FICM circuit board -VGT solenoidWill start and run like it should until throttle is touched then it starts loping if its in gear sometimes stalls.Manually control duty cycle...

Recent oil cooler upgrade, EGR cooler delete, replaced two injectors, went through turbo and completely cleaned it. Before was around 24-25lbs. After getting it back together I'm getting a low IPR code and maybe 12lbs of boost. Initially, was no boost but has gradually come up.

Mine looks nothing like that

2005 6.0, 190xxx miles, stock minus upgraded oil cooler and EGR cooler delete.FICM died, replaced that. After that Had an injector holding 0lbs, replaced that, Pulled EGR valve and went nuts cleaning that. this is my initial video but symptoms are still the same.IPR or ICP maybe...

Gotten to the point that it cycles constantly, even with the system off. I have a good idea as to what it could be but wanted to run it past.What's the most common issues for this situation?

Yeah, 580 lb ft ain't nothing to sneeze at. I've crossed the scales at 21k many times. Knew it was back there but never struggled.Wouldn't mind a bit more grunt though.

Personally, seen good reviews on the Diamond Eyes 4" aluminized system. Can't beat the price.

My '05 does it too. Doesn't matter which back window it is. I have to crack the front window to alleviate the issue...

Maybe with this cool weather I'll have some extra time in the next week or two (Ice delivery, it gets hot I get busy) to where I can swing by and check it out. Looks pretty clean from the pics so might be able to work some magic on that paint as well.I work in Boise, live in south Nampa so...

What's your time table for wanting it done?
