The last I read on a google search was the homologation was taking extra time for oz. That was back in nov. I assume nothing happened in dec.
As far as I know from friends who have had power kits this is done by the dealer. You would have to ask if factory can do it. But if the dealer does it before you take delivery there isn't much inconvenience to you.
