2015 Chevrolet Silverado 3500 HC DRW 4WD
Not sure of the turbo terminology but heard a noise the other day that sound like a blow off or waste gate sound. Don't remember hearing it before. I was coming down a off ramp and accelerated to get into another lane then let off real quick and that's when I heard it. I got it to mimic it again by accelerating then letting of real quick. Is this normal. Sounds kind of like tires sliding side ways when turning fast. Don't ever remember accelerating then getting off of it quickly like that before so that could be why I've never heard it.
