Pair and auto tune
I was thinking about buying the bazzaz zfi and qs for my 07. I have done some searches but cant seem to come up with a deff answer if I need the pair block off with the auto tune. It says I would deff need them if I was haveing custom map done, but do i actually need them since the system is constantly adjusting? Also If I do need them, where can I get them from? Most places say 08 and above with nothing for our years or older.
