Good luck,

uh ohhhhhhh... My turbo is running at .05 Bar... well thats where it sits... (about 7psi) I didnt set it there.... and I have the whistle of all whistles. I mean like it turns heads..... course the whole rig turns heads. I thought the whistle was cool and normal. It does continue at all times once it starts and only stops once I decelerate and reach below a certain point in the RPM. This is the only MB I've ever driven or heard though. At what RPM it starts I have no clue since I dont have a Tach.

Sooo anywhoseee... I have a stack exhaust like a big rig and no muffler. Just a small silencer. This thing certainly sounds to whistle from the exhaust stack and not inside the engine housing if that's what ya mean by intake whistle. Might I have an intake air leak?

83-84?? 5cy Turbo D
