What was so general about my statement? A car will run at idle or regular (non-boosted) driving at practically any afr. You could cruise full lean of you want or dump fuel into the 10's. Should you do that? No but it won't kill it. Yes you want to aim around 14.7:1 for idling and cruising but there are variances that will make that impossible to do that all the time.
Boost is a different story. But why would running .2 more air effect it to the point od being up driveable? Guess what it won't. It won't blow the engine up. Will it be sub optimal? Maybe Idk I dont have enough time on a dyno with the car.
Again I was posting limits, so he could ease his mind. Like "oh its not exactly 11.5:1 no worries" now if it starts creeping past then in full boost then its time to go back to a tuner.
