If it's just the whistle, not the rpm's, it is just the turbo vanes cycling at idle. It's part of the latest Ford ecm flash, nothing to worry about.

Yes, you can add me to the list to tell you that it's completely normal to hear the turbo whistling, as per Ford's latest caibration level 6U7A-12A650-FFE for 2006/2007 6.0L F-250/F-350. Which dealer did you have this work done at, if you don't mind me asking?

Ford Diesel/Senior/Master Tech who placed 2nd overall in Ontario on the Fix-It-Right-First-Visit score for 2010

....who works at a dealership that now employs SOME half decent looking female employees since they overhauled most of the administrative staff

....but STILL loves hot women with big boobies

....and STILL hates working on E-Series with 6.0L
