Hey guys. New to harley, and the "stage" upgrades. Currently my bike (2008 883) is stock except for rush 2.0 slip on's. Dealer (as well as everyone else) says that no re-map is required for just the slip on's. In the spring though, I would like to get the SE intake, which would then require the stage 1 download. So my question is, is the stage 1 download the same thing as the ECM remap? part of it? Others are suggesting going with the XiED O2 sensor plug ins to richen the fuel mixture.....but getting conflicting info on whether those work with stock bikes, or with stage 1 and later......oh so confusing..
