    It is in the owners manual.

    When you say "True" what do you mean? The specs Ferrari gives are not absolute if that is what you mean. They express it using their measuring method which is also listed in the OM.

    Intake is Open 10 BTDC Closed 58 ABDC
    Exhaust is Closed 10 ATDC Open 54 BBDC

    By asking for true, I mean FACTORY settings. I personally use lobe centers for setting, I don't want to confuse TESTAROSSA settings with 512"M".
