Message: [QUOTE="UpstateDieselGuy, post: 225499, member: 3856"] The truck definitely pulls hard. The data log of the VGT Duty Cycle is very smooth with quick changes matching the demand on the VGT, except as he described, when the converter is locked and you roll into the throttle. It begins to lug a slight bit before the fuel starts to hit and begins to cut in and out via exhaust tone. It acts as though an exhaust brake is cycling while accelerating. While this is going on the Data Log is very jagged and it matches the cycling of the VGT perfectly. The sound is very similar to when I would kick in the Tow/Haul with Eric's Towing Tune with aggressive braking in my 6.0L, except that it is cycling. [/QUOTE]
