howdy. as the title says, I have loud mostly single bachfires at 4,500 on decel. This only started after the bike was serviced. bike didn't idle great either. the shop( good rep.) said that I needed to remap since it is now lean. so I just got a pc2( thanks killer) but the cd won't download on my puter. I install anyway, pc2 has the 001 marker for a map on it(full ex system). I adjusted the low manually and has had no effect. Just curious if anyone else has had the same problem or maybe I should start adjusting the midrange. btw, bolt ons yosh, k & n, tre. thanks
