Hi guys. New to the site, but I am having the same backfiring problem. I have a 2008 Roadie S. I put Cobra HP 2 into 1 pipes on; gain in performance, but backfiring a problem. Then installed a Power Commander. Cannot tell any change in performance and still backfires BAD on deceleration, except when it is cold. So far Power Commander was a big waste of money. Was told to increase air volume, (Yamaha tech) so I put a Hypercharger on. No change..... still backfires like a BIG DOG! Any help/suggestions would be appreciated. Thanks.

do you have the right map on the PC for all that you have added? And yes, remove the AIS!! Then take some incense and check for air leaks on the exhaust.
