I think sincro Rev is standard in LEV2 370z M6s, not in Lev 1, maybe Lev2 in Italy, is the counterpart of sport pack in U.S.
I don't know for sure, but i'll call my dealer today !
P.S: can I translate this post in italian for those peoples that doesn't understand English? Because there isn't italian forum about 370z..
Thanks!
Ciao!
