I bought a Vans and Hines fuel-pak for my 08 FXD when I was going to get V&S pipes. That has now changed to Samson pipes. Same type though. Anyway, the guys at Samson told me that the 08 to 10 bikes will automatically remap themselves if I drive it for at least 30 miles without shutting off the bike. Anyone done this yet? I can put it on anyway, but if I don't have to put it on I would rather not.
