Sounds like a loose wastegate, if I had to guess. These cars return wasted boost to the intake tract, yes? If so, the increased noise and the rough running would make sense.

Bring it to the dealer and insist they fix it. Bring it to another dealer if necessary.

BTW, why are you in neutral while going through a sharp turn?
Thanks, probably just a bad habit..
