6.0 loosing power and boost

[workingwoods]

Hi all, I have a 03 6.0 f250 cc 4x4. I had the truck to ford about a week ago, and a week before that. Was loosing all power under hard accelleration. They said it was a cracked fitting on the boost guage hose to the sensor. They fixed it, then reflashed the computer. Truck ran great after 1st time, but tranny shifted really bad. Took it back, they reflashed the computer again, and said it had same code as before, and that they didn't clear it right. Now a week after that, the truck is not running well. Seems to have lots less power and the boost guage NEVER gets over 19-20 psi. But the truck isnt loosing complete power like before. any Ideas would be helpfull before I spend the money to take it back to them agian.

I've only had the truck for a month and I may be regretting my decision to get the 03.'

Thanks
John

Sounds like a turbo issue to me, but I'm no expert. I mainly wanted to bump you post up.

Thanks, just to add to the post, I also hear a HISSING from under hood when truck should be making boost, but cant find any leaks in rubber hoses or intercooler, I am going to try carb cleaner tomorrow to see if I can find anything. Might try to unplug VGT and EGR. See if any difference.

Thanks John

Take it back and get them to trouble shoot it.
