The 66 VGT has me wondering , as long as you don't see 15 on 2500 rpm and 85 on high idle , you will from time to time get 85 VGT on low idle , is this test in park ? Need to be in park no HVAC, radio, just getting the values in koeo low and high 2500 in park, the ICPV when the truck is acting up try to get those numbers, at what rpm we can guesstimate unless you capture these in park 
, could very well be an injector, just trying to rule out some obvious parts that do the same thing in Nature

I could've had it shipped here for same or next day but I figured I needed the ride in my 6.0. I wanted to try the Sea Foam before I dumped the oil and added Rev-X with fresh oil. Stuff ain't cheap though. 39,98$ CAD a bottle. Hope it helps.

I captured these in PARK with only the lights on. Now, ICPV range from around 0.28V to like 4.something, even 5 if I recall correctly and it matches how much I put my foot into it. I haven't seen it bouncing around other than small normal decimals. Can't really hold it perfectly still.

I was juste watching some more youtubes from Bill Hewitt and there was one where he talked about the replacement injector options and he explained stiction. After watching this, I'm getting the feeling that I am experiencing stiction on the fuel side of the injector(s). IF, that's the case, Rev-X in my oil won't do much other than prevention which is still good. But IF, that's the case, then I'll just keep using ATF in my fuel for another 3-4 fillups or Sea Foam the pee out of my fuel until either A) the pesky varnish problem goes away or B) I stick 8 new injectors in ´er and be done with it.

Okay I see.

Okay! Seems there might be a happy ending here but I still remain sceptical until tomorrow morning.
My issue so far was:
Missing, spuddering, hesitating [I]after[B] cold start and warm up.
Getting better as the drive progresses.
Getting back to spuffering and bucking after standstill.
The fact that my truck started great in cold weather got me thinking that stiction wasn't the issue, either on the oil side or the fuel side.
FICM voltages were great across the board.
ICPV, ICP and IPR values were top notch.
Turbo runs fine.
Haven't got my fuel pressure gauge yet but everything leads me to think it is not the issue since plenty of power and coal at hard take offs and hits 120 MPH no problem.
Now, today, I went to the parts store to pickup 15 liters of Rotella T6 5W40 and filters for my truck. I took everything along with my Rev-X to my friends shop. He agreed to let ME do the work because I wanted to check EVERYTHING as I did it i.e. air in the fuel bowl. TURNS OUT there was! So I got one of his guys to cycle the key to watch for bubbles, nothing came out for the 1.5 seconds it took to fill the bowl and make a little bit of a spill. So I put the top filter in and left the oil filter out until I drained the oil. I wanted to put the Rev-X in the filter bowl.
So I lift the truck up and unscrew the lower fuel filter cap. It wasn't hard to unscrew AT ALL! I inspect o-rings, put the new one on, screw the cap down to where it can't turn no more, then tighten it just a little. I feel that was more than it was before I took it off. I then drain the oil, put the plug back on, drop the truck, in goes the Rev-X, then the oil filter then the fresh oil.
I then get in, cycle the pump 4 times, start it, park it outside to pay the 20$ to use the shop and leave right away for a road test.
NO SPUDDER!!!
Rev-X can't be THAT instant. So now, I am suspecting that loose fuel filter cap underneath. Turns out, the truck has been acting up between the last two services and they were performed by the same guy. I'm thinking he just did the old "screw the cap ´til it touches plus one quarter turn on the o-ring.
But like I said, I'm still sceptical. We'll see tomorrow how it works.
