As has been discussed multiple times in various other threads, the S55 at 431hp is most likely underated by 20-30hp, if not more. This has been demonstrated with most other FI BMW engines.
I am looking forward to see some real world data (acceleration runs/dynos) that will indicate the actual power that the S55 generates.
