Hello guys!
Remember, I'm not here to stir up the pot but I'm trying to force my brain to wrap itself around what I'm seeing here. Well, more like hearing actually. Watch this:

If you're listening carefully, you'll hear some rattling under acceleration. It can't be off-throttle blowing because it's happening while accelerating, and the first thing I thought was a form of TC. Or a special engine map. Can somebody with background knowledge go into this and explain what we are hearing?
