My 2005 F-350 has had issues with putting a load behind it lately. If I have at least 5000lbs or more behind me and I get on a hard pull up a hill the truck will put itself in a limp mode, light comes on and it wont build over 12lbs of boost. A friend of mine hooked his diagnostic tool up to it and the code said something along the lines of a supercharger over rev issue. He had also said the limp mode issue may be due to it defueling itself from building to much boost. All of my turbo hoses and lines are in good shape. Has anyone had this problem or know about it, feedback would be appreciated, thanks!
