Where can I buy this O2 controller? Didn't find it in the xt660-store? Do I need something else? I have a GPR powerjet (some sort of a power commander) and BSM-exhaust and K&N filter on My bike.. In slow speed the bike is a litle bit jerky I think..
Want to get rid of that if it's possible.

What's the difference between the o2-eliminator and the o2-controller? Have not found that information?
