If you're looking for a "chip" like the ones used in some automotive applications - I don't think they exist, since there is no "chip" to change out you have to access and unlock the bikes ECM and change the programming in it.
A lot of us here use the TTS MASTERTUNE. You could give them a call to see if their system will work on the 2013 Breakout CVO.

If you're not upgrading anything else on the bike you won't need a tuning device, just ride it
What else are you planning? Exhaust upgrade? I hear the choices are limited for the Breakout?

If so perhaps the maker of the exhaust you chose can recommend a tuning device. You could also probably purchase the HD SEPST through the dealer and have them tune the bike.
