One thing I have noticed immediatly (which I took a recording of on my phone), is that there is now a resonate "chopping whistle" sound or something, which seems to come from the drivers side, at the front - possibly from under the car or from behind the engine.
You can listen to the sound here:

At first it may sound like wheel spin or chirping, but it's not. It's only when I'm at WOT on full boost, and I'm sure it's only during some part of the rev range. I think it's just a resonance of sound or air or something.
