Hi Guys, I'm new to the forum. So here's my issue, I am wondering if anyone has had the same issue and knows of a fix: It started about a week and a half ago during some very cold weather (-10 F) and the turbos were blowing off 5-6 times repeatedly under acceleration. I thought it might just be the cold weather and it still ran/accelerated fine so I was hoping it would work itself out, it did this just about every time I drove it from there on out. Against my better judgment I drove it to Canada this weekend for a fishing trip (about 400mi round trip) towing 2 snowmobiles. On the way back it seams that I have lost all boost and instead of a normal turbo whistle with a blowoff its turned to a constant whine (sounds almost like a supercharger but louder) and no blowoff. Acceleration is terrible, currently its parked at home till I figure it out. Anyone experienced this? any thoughts or fixes? Any help is much appreciated.
