Pulling a load up hill, diesel/turbo screaming and only going 35MPH floored. Was told everthing checks out. Coolant looked and smelt burnt. Was told the pcm updates would fix the problem. Any advise?
Welcome to FTE, Rick. Sorry to hear about the problems.
The coolant smells burnt? Is that when you sniff the open degas bottle? It should smell kind of sweet, but not burnt. In fact they put a bittering agent in it so kids and animals won't drink it because it smells kind of good.
What color is the coolant. Should not be green, should not be orange, should be kind of **** colored.
I cannot imagine any new PCM flash correcting that issue. Stupid answer on their part if you ask me. I would be looking for another dealer, IF it was under warranty.
Almost green. No black smoke at the time. Got a little hot but nothing major.
Wrong stuff. These trucks should have Motorcraft Premium Gold, or equivalent. Definitely not green. Of course, that alone won't cause the power to be down.

How much load and how much hill? Have you pulled similar before?
I pulled the same load same hill about a year ago and climbed it 65 no problem.
Coolant is not the problem. When did you last change your fuel filters? I believe if you have it floored with the turbo screaming you should have black smoke coming out of it. If you have little or no black smoke, you probably have a fuel flow or fuel quality issue.

It is possible that the PCM limited the power if it got too hot.
