Getting my fat boy serviced soon have been told I don't need to bring the tuner kit with me for the service unless adding new mods. Just wondering if that's correct or not?

There digital technician will scan any problems with the bike. There right you don't need to take the interface for the ECM unless your planing on a dyno tune or engine mods. What mods do you have on the bike for a race tuner

As far as I know I only have S&S pipes.

 Have only had my bike for 3months and am new to Harley Davidsons, but farking love it. The bloke I bought it of just told me it had a race tuner kit fitted to get things rite with the S&S pipes.
