Help! 06 6.0 No power no boost subzero Temps.

Visiting friends up in NH and having problems and can't get truck home. Truck started out the day fine yesterday. High temp was about 10 degrees. Drove about 60 miles up into the mountains and on the drive home was down to -9. The first 75 miles of the drive home went fine but truck then started losing power on the highway. Thought fuel was gelling so I dumped a bottle of 911 in it but now I don't think that's the problem. Truck starts and runs real rough. It won't boost and can't get it over 40 mph and most the time it will only do about 20 and blowing lots of soot. Going up hills it completely bogs down and black smoke pours out from under the hood. Eventually turned around and went back to my friends house but now I'm stuck 150 miles from home.

have you checked your IC boots? a crack or split or blown off one can cause a whole lot of problems for these trucks. BUT having soot come out from under the hood i would have to assume you have a bad up-pipe bellows behind the turbo. have you looked with a flashlight back there to try and fine a source of this soot? how is it idling?

Yea if black smoke is coming out under the hood, that pretty much narrows you down to something exhaust related....blown bellows in uppipes is very common.
