What would be a better choice? I have an 06 1000rr with a Two bros pipe, would it be better to go with the PC III USB or spend the extra money and get the Powercommander V and the Auto Tune module?

 

They dont make them for the older bikes. Only for 09 up (but will work on 08 cbr1000rr)

 

DONT GET EITHER.....get the bazazz unit and get the ato tune unit from them...i forget what it is called right now but it maps automaticlly based on what you tell it you want your air/fuel ratio to be for each individual cylinder for each gear.

 

Tbagr is right the Zi-Fi fuel control unit and the Z-AFM fuel mapping kit is a real good combo... these actually auto-map without the cost and time of dyno tuning. (since you're looking for the auto tuning,as the user rides the bike, on the track or on the street, the Z-Fi automatically calculates the required fuel adjustment at each RPM and Throttle Position to reach the user selectable target air fuel ratio)

It just depends on how much you wanna spend also?...Bazzaz Zi-Fi ($399), Bazzaz Z-AFM ($350), PC3 ($265) or Two bros Juice Box ($300).
