From what I've learned, generally you shoot for afr based on your meth/water mix. There is a great thread on this in here if you search for it.

100% meth: 11.0:1
75%meth/25%water: 11.4:1
50/50: 11.7:1

The best thing to do is put it on the dyno. Run it at 11.0, and then lean it out and see if it makes more power. You may be able to run more timing at 11.0 vs 12.0 also, see which works better for ya.
