I bought an aluminum LeoVince can which comes with an O2 bung installed. The Autotune unit comes with an O2 sensor. Altogether the rig cost me about $800, but I feel it's worth the money. I realize it's a bit expensive, particularly if you only plan to keep your bike for a short time (it's likely you won't get much extra resale because of this mod or any mod). I tend to keep my stuff for a long time. Even if I didn't keep stuff, I really like having as much potential in a bike as possible. This mod has smoothed out low throttle opening choppiness completely and made the bike a pleasure in town, as well as when shifting through the gears when touring lazily in the country.
Several members here have done the same thing. Search around as see what they think of all of the available systems. They are all an improvement, from what I hear.
