Well FWIW, today I had my 1200 mile service. Our son works at the dealership, and took it in. He asked both the lead tech and another very tech oriented member of the team. Their answer, to the performance unlock was: slight RPM raise, and the enabling of launch control (I assume DCT only, which we dont have?). Who knows I do not have data to compare before and after.
