OK here goes. I have a 13 ultra that has tru duals, hi flow air cleaner, and a automatic tuner. When I had the local dealer install cams they put a download in. My question is this, Should I put back on the tuner or just go with the download. And if I do put on the tuner will this take my download off the ECM if I remove the tuner. Sure hope that made a lick of sense.
