Well if it is edited to disable (0'ed out) the P0101 how did you get one, did you miss something?
Maybe, but if I did, I can't find it. Everything that should be zeroed is.

You could try this 811 Stage IV Hot Tune, I had Yeti modify it for me a few months ago to remove the P0101.
I was getting an occasional P0101 on mine on very hot days (100+) when pushing it a little hard.
Have never gotten the P0101 anymore after he zeroed it out.
Yeti's 811 EGR/FCV/MAF-P0101 delete + Stage 4 Hot tune (vers 1.02), link-

Interesting - when I was testing this yesterday, it was over 100°F out. Will give it a shot later; made some progress this morning and want to see where that shakes out first. Here's what's been done:
- Replaced fuel filter with another Mahle KC182; primed with Diesel-Kleen
- Reset all DTCs
- Reflashed ECU
- Filled up with exactly 19 gallons of fresh diesel
Hand-calculated mileage on the last tank was 18.8mpg (358 miles on trip meter at fill-up); average is usually closer to 23-24mpg.
Went on a 20-mile test loop. Soot is definitely improved, but still way more present than I'm happy about. It doesn't tend to appear during acceleration at speed, but taking off from a stop almost always produces it. Performance below 1600rpm (particularly from a standstill) is still sluggish, but is better than it was. No DTCs, which is a definite improvement.
Found the cause of the water in fuel sensor code: the connector had worked loose. I'll blame myself for that one; must not have got it fully on at the last filter change and just didn't notice. It definitely clicked into place this time, however.
Overall, I'd say it's about 90% back to normal. Going to drive it for a day or two and re-check everything now that it looks as though things are starting to move back towards a baseline.
