So i went to go pickup my 2007 f350 king ranch 6.0 dually when the check engine light came on and the dealer said the code was low boost. So they currently have it in the shop and said they are cleaning the turbo. Does that sound normal? The truck only has 46k on it and im paying $28,500. Should I run? The oasis also said it never had warranty work. The truck is almost spotless.
