Only sync'd to my 99 TA and about the only thing I did was change the gear ratio when I bought a 3 series rear end (Had an auto with 2.73's to start with) and deleted the rear O2 from the passenger bank when it went out...

Is 350 shipped 2 day too much? If they had any questions I would be more then happy to give them the serial so they can contact EFILive and make sure it hasn't been use to upgrade to V2...
