RPM fluc
At about 1800-2100 RPM's at about 40-50 MPH I hear my engine fluctuating. I looked at the tach and can tell that the engine is fluctuating. I can't feel it though, I can only hear it and see it in the RPM's. It's not a really bad fluctuation but you can hear it, espeacially when pulling a hill. Does anyone know any suggestions???

I called the dealership, the man I talked to has worked for Ford for over 40 yrs. He is a diesel expert, he said that the actuation control for the turbo is on the edge of giving it more turbo and there is a fine line between needing more turbo and not. He said that several trucks have been in there with that and that is what Ford is telling him. My oil level is in the middle of the dipstick when the truck is warm.
