Hello Diesel Peeps, Recently on a trip back from Tenn hauling a gooseneck flatbed with a 4000 lb tractor I experienced a sound from what I believe out of the turbo. Its kinda sounds like air huffing or pulsing from the wastegate possibly. My question is....is the wastegate working properly or is this the signs of failure....No turbo upgrades have been done to this truck, it has now 201,000 miles....4 inch exhaust , Big air filter, SuperChip download off road tune, 33 inch 17 wheel 4x4, Banks Trans controller..........any and all help or input to solve this problem ...Thanks
