Hi new to the site,just a few questions about an 04 ultra,stage1. when I bought it the stage 1 and true duals with S.E. air cleaner were already installed. The bike had 17000mi on it.I've since that point went with a 2 into1 Rineheart,.question is since a stage one download is in the ecm,will I need a new one because of the 2into1,.also added a power x-wing at the same time as exhaust,.local dealer claims downloads are no longer availiable,.also told me to just monitor plugs and if it runs well it should be ok.,..plugs look very light tan,.[S.E.plugs] bike runs great,.much better than before,.any thoughts?
