Hey guys, i am in need of some help. wednesday afternoon i put the stock tune in my truck to move my 5th wheel to go camping today. I left the stock tune in because thats what i was planning on pulling the camper with so thursday morning heading to work i hear a whining sound like a supercharger. The more i press on the gas pedal the louder it gets. So i put a economy tune in it and it ran great. No whine or anything. Put the stock tune back in and it starts whining again. I have now power loss or anything. Runs great besides the whining sound. Could this be the turbo going out? Or is there something else i can look for? Somebody told me the turbo but i have no loss of power at all. Thanks guys!
