My 03 has a power commander, full muzzy exhaust, and K&N filter.. has great power but when i let off of the throttle it pops and crackles, sometimes so loud and hard it shuts off.. when i bought the bike it had an 02 full muzzy K&N filter map.. the guy told me there isnt an 03 map.. or atleast he cant find one.. any ideas.. maybe a different map that is recomended.. o ya and the neareast dynojet program place is 4 hrs away..so if anyone has a solution let me know im tired of getting wierd looks when my bike sounds like a shot gun going off..
