Ok when I started my car it sounded much deeper than usual, also when I tap the throttle, I get a high pitch squeak that sounds like a BOV coming from the turbo area. Exhaust leak? Not sure if this is too vague but this is the best I can describe it.
Edit: I just went out and revved it in neutral. It sounds like it's sputtering when i rev to about 3.5 - 4K.
