Anything around 11.5's is great, get over 12.0's and you start walking the thin red line.

AFR's can go as lean as 12.5:1 and be entirely safe, its moreso your ECU and the speed at which it can interpret wideband readings to make corrections that determine whether its a good idea for your car or not.

most people opt between 11-12:1
