Well it seems decent. What you might want to do, is get a gauge, (this is the cheap way) and when you are cruising it should be at "stoich"/"lean". When accelerating it should go to "rich". A wideband A/R gauge would be best, but they start at $300 + welding a bung in the exhaust. (they are used for tuning engines, it would be useful if you want to tune your afm).
If you really want to get the most out of your engine, you could pick this up http://www.yotatech.com/f107/msii-v3-0-22re-harness-180714/ which is pretty awesome and fully user-tuneable.

Oh Ted, remember that guy "thief" that was here many moons ago, that had 161whp 22re? <img src="/forums/images/graemlins/smile.gif" alt="" />
