Turbo might have to be replaced but problem could be with the 'Exhaust Brake'
The 6.7L CTD uses a Variable Geometry Turbo.......vanes that move creating back pressure/exhaust braking
The actuator is usually ok, its the nozzle ring in the turbo that starts to bind. The servo motor isn't that strong, so any galling or buildup on the sliding surfaces of the nozzle ring will cause it to hang.
Does your MOM even turn EB ON??
If not routinely used it binds up due to sooting.
YEP, start truck turn on EB and TH. Wash rinse and repeat!!!
