high pitch whistle ?
My F350 has got a very loud high pitch whistle, at part throttle in below freezing temps. It seems to be very throttle position specific, esp. from a stop under normal acceleration. any ideas? 26000k just love to drive this thing. as a side bar, all the talk of fuel milage with the dpf regen using fuel, it could be worse. We could be filling a urea tank every week too.

this is not a turbo sound, my kids say it hurts their ears. it is very high pitch, like a tuning fork. the noise is at any + throttle position, back off and it stops. if you really put your foot in it, it passes it (around 15psi-20 makes the noise). some f150s had alternator problems that sound like this. I just had the rad and pulley changed last week, now I'm going to look like a complainer to my service mngr.
