I'm planning to add the HD Heavy Breather and a V&H ProPipe as a start to my Stage 1 on an '08 Road Glide. Provided I'm going to do those myself, and have a dealership do the download -- Which way am I less likely to do any damage? (1) Do the mods first then nurse it to the dealership (about 15 miles) for the download, or (2) Have the dealer do the download for my planned changes, then nurse the bike home and make the changes? I understand in either case to avoid any hard ride until it's all squared up to each other. Thanks!
