i have the exact same question as you. i already bought the exhaust and intake but am afraid to install them until i know more about this efi system. do i need a tuner or the download? and if i need a tuner, which one should i get if i plan on putting carbs and a bigger bore on the bike some day?
2006 fxdwgi, planning on installing the V&H sideshots with a forcewinder XR-2 intake. anyone out there with some help on this please speak up. dr. dyno, maybe?
