alright here is the story i have a 05 busa, i bought it from a buddy of mine it had 4000 miles on it, the bike ran great but the FI light was on, so i scan the light and it came back to a C22 code. I ordered the ambient air sensor, along with a 4-1 exhaust, while I had the bike apart I just figured I would do it all at one time, so i changed the sensor, put the 4-1 exhuast and done the airbox mod, now the bike has a horrible misfire below 4000rpms, but once it gets to about 4000rpms it just takes off and runs good. It has no FI light and no codes now, im thinking that it maybe the map cause I put the exhaust and airbox mod, im thinking I need to get a power commander and remap it and that will fix the problem but i want some more input before i do that. Thanks
