Looking for assistance started truck today Turbo not working engine starts runs but no turbo. RPMS higher and when stepping on accelerator engine bogs down. New to DuraMax so not sure where to start with this issue. Truck has 92,000 on it. Thanks!!
If your truck is an 08 you are likely running an lmm, not an lml... that said I would check the flex couplers on the turbo outlet... if your wheel is wrecked you would have some quite nasty sounds along with the lack of boost.
