Had my truck in the shop the other day to get the FICM replaced. They told me this code also showed up and "turbo under boost code - could be caused by power loss due to above problem (FICM), but could also be separate issure down the road with turbo".

Has anyone else thrown this code, what is/was the cause and what was the repair?

Thanks for any help.

 

Definitely sounds like a sticking turbo. If it's under warranty it should be cleaned or replaced by your dealer, depending on the condition of it. If you're out of warranty, I'd try cleaning it.
