No CEL? Maybe a exhaust leak, pre turbo? Like manifold gasket. Although you would probably hear that.
so i have a 337 with a giac tune. I got on it today and noticed it was only boosting to 6 pounds Does anyone know what this means? i did try searching but didn't seem to find anything. My first initial thought is that its in limp mode, but wouldn't that only restrict me to 5 pounds of boost? I did get my turbo taken out like 4 months ago to get one of the studs replaced, because it broke when i tried to take the down pipe off:bang head: but other than that the car has been acting fine.
I do also have a squeaking noise coming from my motor, sounds like a belt.
Any info from you guys would be very helpful.
