The dyno posted by Ponyboy here http://www.nsxprime.com/forums/showthread.php?s=&threadid=32378 got me thinking. What is the optimal A/F ratio for NA engines? To me, the a/f here on the dyno(~13.5) at the top end seems to be about perfect for N/A engine. Go leaner than that and it'd be dangerous even for NA engine I would imagine. But would there be any benefit in richening it up a bit on the top end?

Also, if you are to advance the timing at the top end, would it help much?
