| Read the "Power Commander Question" thread in this forum. We have been over some of this already.
I had a similar question about variance from the equipment stipulated by the maps on the Power Commander website. I called their tech help line, and the guy told me which map would adequately substitute for my intended combo. Check it out that way, but in any case, I think the forum here recommends a dyno session after you install the PCIII with your new pipes. The PCIII is easy to install and to map.
Read my own saga on this same thing under "Pythons on a Softail". Keep us up on your progress so we can all learn something good.
