What AFR is your Tuned NA S2000 running at?

I'm just wondering what afr you guys are running. I'm tuning for 13.5:1 but I'd like to see how other people have tuned their cars. Please also post a little information about your setup and how much you dyno'd as well.

how do you know its running at 13.5 when you haven't been on the dyno? do you have a w/b in the car?
