turbo problem accelerating

[diesel_dude67]

recently ive been offroading (couple weeks ago) and went through a big hole where the engine ingested some water. limped it back home dried everything out and nothing was wrong for the first week but now on acceleration up hills (around 22 pounds boost) the turbo will rapidly move beteewn say 18-28 pounds boost and puking black smoke on the high end of the boost. other than this the engine idles and runs perfect still, what could be the problem?

i should also add this happens only for 30 seconds or til i stomp on it and im in overdrive as well

Not sure how to stop it on a 6.0, idk if the Wicked Wheel is made for you turbo. A tuner helps.

no, but the water more than likely ruined the inside bearings of the turbo. or the Variable vane mechanism, and its having trouble operating.
