The 11.x ratio is seen driving down the road at 35 in the 'burbs or 65 mph on the highway. I've never been deep into the boost yet because I don't have a BOV (M6 tranny). I'm picking up a Tial 50mm tomorrow during my lunch hour.
The air/fuel ratio in a normally aspirated street car comes in around 13.5 to 14.7:1. On a turbocharged car, a richer ratio of 11.5 to 13:1 is ideal, but that is in the context of boost. I'm driving around on the highway pulling 14 inches of vacuum.
