I have a 03 f350 6.0 and the turbo cuts off at about 15 to 20psi and stuggles the restof the way, but if floored it it will work fine. Not sure what might be causeing the problem any help would be great.....Thanks

I was told that the 03 6.0L were not the best. You will most likely have to go to the dealer. There are about 15 computer reflashes for that truck. That may be you problem. Also 6.0L will not move if it is having a turbo issue.
