Have a question about my turbo spooling up. Issue started on a trip from Atl to Maine pulling a 8.5x16 enclosed trailer (approx wt. 5-6K). Toward the end of the trip the boost wouldnt come up... you could feel the engine lug, I'd drop out of the thottle and get back into it and you would hear the turbo spool up. Been doing this for about a week or so now. Seems to be doing it more often too. Power and mileage seem to be going away as well. Not so sure about mileage because I just went from a 4" lift and 35's to 6" and 37's.
I am thinking my turbo is going.... any thoughts? Truck is an 06 with approx 69K. Running DJ's tow extreme when it happened, loony wild back in Atl. Heads are studded and running 4" exh w cat deleted. Other than that the truck is stock
If turbo is shot, what turbo should I replace it with, not going back to stock.
