Look behind the Front bumper and intercooler of your truck, I've seen one truck come from the factory with the quick release clamp loose coming from the blow off valve hose. It may be loose just push it back on and you will hear it "click" in.

Def check the hose on the blow off valve as MGM suggested, I actually disconnected the hose on mine and sealed off the port to the intake just so I could here it. I could never hear it before doing this. If it is loose or disconnected, you could be sucking dirt/debris into the intake, not good. The BOV is on the bottom drivers side corner of the intercooler with a big black hose running to the bottom of the intake tube.
Here's what mine sounds like with the windows down:

MGM, Alping, Spectre - thanks for the informative responses, I'll check them out. And dealer #2 agrees there is an issue.

So****, RickTurd, and BlackDouche - you just won the internet, congratulations.

These sound threads remind me of this video.

MGM - sure enough the hose was off. It is now on and the truck is quiet as it should be. Thanks much, you saved me significant effort to get a dealer to figure out. Now am wondering if there is any damage to the turbo circuit.

I read this, laughed pretty hard, went and read a few other threads then came back because I was still laughing. Greatness.
