I have an 03 Vegas with Stage 1 map, that started the popping & backfiring crap & running lean. So I carried it to my local dealer who said that the bike had lost it's map & needed to be remapped and tps adjusted. So I told them to fix it & they charged me for a new calibration card & tps cleaning & adjustment. It runs so quiet now you can hear the motor over the exhaust,it lopes and has no power. They don't want to stand behind their labor warranty, so I'm looking for input on a fuel controller & any ideas on what the problem maybe.
