It won't do it sitting still but as soon as you start to move there will be this weird whistling noise, which sounds a lot like air getting around a window seal when you're going down the freeway.

When I give it gas in park it doesn't do it. As soon as I put it in gear and start driving it does it. It's not the turbo whine. It literally sounds like air is getting around bad old window rubber going down the freeway but we're talking about going 5 mph in the parking lot here. It's mostly under acceleration.

 

boot on intercooler blown or leaking.. top intake plenum gasket leaking??

 

What he said....also, check your kickpanel vent, or on door inside your heating/ac box under the dash, sounding thru your ac or defroster vents.
Those sounds can drive ya batty trying to find them. You also could have lost a piece of weather stripping on your door. Check your door vent also.
