I just installed a COBRA power flo air cleaner, FI2000 power pro tuner and COBRA pipes and mufflers. Im getting backfiring when I back off the throttle. I've got about 60 miles on the exhaust and wondering if I need more time to have the tuner cycle and cure the problem. Any ideas?

The newer Fi 2000 don't have the adjustment pods so there is nothing you can do. If you don't have a exhaust leak you are most likely running to lean on decel and you need to have some fuel added on decel.
The older styler Fi2000 have adjustment pods and it is easy to adjust.
You may consider taking the Fi2000 off and take the bike to HD and have the ECM reflashed than re-install the Fi2000, it may take care of your problem.
