Keep it simple grab two power commanders bring it to a well known tuner in your area and tell them what each bike is going to be doing.(track or street) You are going to spend hours upon hours making adjustments with the Bazzaz auto tune. For people to say that Bazzaz units are the only ones that have issues is pure b.s any electronic piggy back to the ecu can have potential issues but that's the chance you take putting these things on. Do you really need a quick shifter and tc? no you don't need it. Do you want it because its cool? yes
Your the one spewing garbage after we gave our opinion.
