Scrooged!!-low boost, no power
I am on a Christmas trip in the Texas Panhandle town of Amarillo. Yesterday evening, I noticed a loud "whishing" noise coming from the passenger side of the engine compartment, shortly after merging into traffic and laying on the throttle pretty good. Now all the sudden, the truck won't build more than 15-20lbs of boost nor make it up to anything over 45MPH. Yep, Merry Christmas to me huh?
Any ideas? None of the boost tubing or hoses are loose. Are the vains on a turbo stuck? No way I can drive it back to Dallas like this.
I have shut it off and restarted a number of times and it doesn't seem to have the high idle as if it were stuck in Regen.
It has 4500 miles, F250, 4x4, and was reflashed in November for the REGEN issue.
Thanks for any ideas vs. camping out at the dealership first thing in the morning...

Update: Tech says it is a faulty exhaust temp sensor. Of course, they don't have any 08 sensors in stock, or in the area for that matter. Plenty of 07s and back though... They are having a new one overnighted and hope to have me back on the road by noon Thursday.
I have not seen this in any other posts as the culprit to the symptoms I described, so I am keeping my fingers crossed that it is in fact the cause of the problem.
Question: Could the air escaping sound between the turbos be a blowoff valve open and that is part of the programming--the bad sensor is causing a "protection" mode and thus no boost?

Still stuck in Amarillo, which ain't too bad since George Strait wrote a song about it...
