I was just talking with one of my neighbors who has an "06 F350 SRW in really nice shape, and they love the truck, but in conversation she said that they have had the turbo replaced 3 times on it. She said that they really don't drive it that much... it only has 40000 miles on it now. IIRC, the turbo's on these really don't like to sit, which if true is probably why they've gone through 3 of them. This brings me to my question: Why don't the turbo's like to sit a lot? Also, '06's are not known for their turbo problems are they? This just got my curiousity going.
The unison ring is bare metal, and the vanes that sweep across it will eventually corrode onto the ring. Stuck vanes causes over or underboost, causing problems.
Replacing the turbo three times might have been overkill, a rebuild might have sufficed. But that's the price of not knowing; you can pay for parts swapping and not real repairs.
Thanks guys! All three turbos were replaced by the dealership, under warranty. The same stealership now has told her that these were really not very good engines, and they would like them to trade the truck back in for a new one. She laughed and said no way, she loves the truck. I told her to drive it more! They have three full size Ford trucks and the other two are gassers. This one obviously sits too much. Mike

Lots of posts about this issue. Most include getting the turbo up to max, allowing the unison ring to rotate properly by "getting on the throttle" hard.
After I pulled the under boost code myself, I make it a point to... As others have stated before, " drive it like you stole it" once in a while.
