I am tossing around the idea of getting the ThunderMax EFI Wideband Tuner. Anyone on the forum using it, and if so what do you think about it. I figure ThunderMax might be a good idea, considering the closest EFI dyno is 90 miles away, not to mention my PCIII going bad and running the bike way to lean! Have a V&H FuelPak for now, if it stops raining I can try it.
