06 w9 drone under load

Yeah 10 4.currently doing some "charity work" for the national guard, so itll be a week or so till i can get back up under it.thanks for the hope.like everybody else whos spent god knows how much money chasing a gremlin, i appreciate the ideas.

 

Truck has 7" straight pipes,nothing between turbo and top of stacks(13'2")

 

Its different than that swaan.all my trucks have been straight piped without these symptoms.i appreciate your opinion tho.truck had one of the KW under bunk mufflers on it when i wrote the check,current issue was present at that time.respectfully.

 

Nothing has changed during the 130k ive put on the truck since i got it.like i said it did it when i got it with 450k.id think if something were going to fly apart,or if something was nearing the end of its service life (bearings,worn shafts),it wouldve done so by now.correct thinking?
