For the most reliable power, you want to shoot for an AFR no leaner than 13.5.. The leaner it is, the more power you make, but as a result you sacrifice reliability...
Put it on the dyno and tune it...

A VAFC is only as good as it's tuner.
It's great that you picked up a wideband, but I would really recommend you find an experienced tuner in your area to do the tune. Post in your local forum here on s2ki and ask for a tuner recommendation.
It really isn't just about trying to lean it out as much as possible...I've seen a very skilled tuner take an nice lean tune, add some fuel back in the right places and make more power.
