In what rpm area and load? N/A engine or boosted? Street cars can run 14.5 or so in low load (cruising) area of the map.
N/A cars make best power around 12.5 to 12.8 but that is too fat for normal driving. Cars idle at 13.5 to 14.7.

most cars I see like to be around high 12.8-13.2 NA, I always put more in before I send it out to the street though, every car is different. I notice AFR headed cars like to be at 13.8 for max power..... Weird.
