My PCIII is custom mapped to a micron high mount pipe. Because of foot room, I have ditched the high mount and gone with a standard mount. The can is the same, all I changed was the midpipe (shorter and fewer bends). I can't really tell if it's running different or not, I think I'm so worried about it that I've convinced myself it is. I'm concerned about my bike running leaner now because it can be very harmful to an engine. Is the change in midpipes significant enough to warrant paying another $300 to have it remapped or am I being overprotective? Does the bike have to be so lean that it has a noticeable effect on performance in order to be damaging? Thanks for your help.
