I thought they would need to download a new one, but the shop didn't think it needed it, and it runs great..... I have to admit, I haven't spent much time on all the dyno threads, so I probably need to do more reading, but I didn't think it was necessary.
Can the shop tell what map is already loaded?
I got the bike from the original owner with about 1200 miles on it, and he put the new pipes on and may have had a new map downloaded then...
