I am playing around with an old Arlen Ness bigshot which looks the same as a EJK. My 04 has a k&n filter and screaming eagle pipes right now. I think the bike ran better without the EJK on it. Does anyone know what settings I should try before I waste a bunch of time with this thing? Is this the same as a CFR Fueler and can I use those settings I found in the sticky above?
