Eric Buell Racing offers them for $250.00. I just installed one on my 09 XB12 and man what a difference! The flat spot just off of idle is gone along with the decel pops. Power is in your face and runs fantastic. If you get one be sure to do the TPS and IAC reset as posted by Rainman64. This was an easy plug and play. I have not messed with or have any experience with remapping and really do not see the need to after installing the EBR unit. Hope this helps. Crewdog
