    I have a 05 Ultra w/ Rhinehart, big bore kit, big sucker, cams, etc. and a PC3 with maps I have got from them but I still have to add some to the top 1/3 of the PC(button) to get it to run well. My question is does it matter that the ecu has not been updated? Thanks

    The ECM update / download would richen up the base map and would give the piggyback fueler more on the top end no doubt. How much is another story.

    It runs really well now w/ the button adjusted so should I just leave it alone. Was gonna have it done on a dyno but they want 350 bucks and i am layed off so that's gonna wait till spring. If I can get it there should it have the update first? Thanks Again

    I would prefer to tune it properly with just a tuner because it would be a bit of work mapping your PC with the download to set it up right. JMPO
