Hey, did you figure out what the problem was? I also cannot replicate the sound when the car is parked and I rev the engine. It happens only when I drive and any boost is built up.I'd say this with a grain of salt, I had this whistle appear months after I bought the car and had removed and re-installed the intake a few times for other projects. I replaced DV with TurboSmart PB with no change.
It won't happen at idle revving it because it's caused by boost. When you are driving it should show up right around when you go from vacuum to boost building.
Here is another video of the whistle sound. It seems to be getting louder!
