You bought the SE tuner with yr bike then? They will plug it in to yr bike & load a stage 1 fuel map into yr ECM (due to heavy breather & pipes). Probably just the base map for starters. Your bike should run a little better & smoother. You will get the little orange VCI (tuner) in a box when you get yr bike - don't lose it.

Head over to the EFI section for more info.
