bump...taking offers. keep in mind this was upgraded to 2.0 with the G3 board, and for those who are interested, you can purchase the JB4 G5 module for $150 extra as well as the $5 power wire and have this converted to the latest model JB4...still significantly cheaper than buying the JB4 new at $480 as listed on their website.
(note: for those a little squeamish messing with the harness, burger tuning will convert a JB3 to JB4 for $175, you just gotta send it in to them...still not a bad deal)

or just keep JB3 as is!
lord knows its a ton of power
