ALL the 2012 I have dynoed have been borderline lean to lean , even a couple stock Foci and knocking
Unless you know what the air fuel is and spark knock I would use extreem caution modding the 2012 Focus
I know you mean well, but kind of an absurd thing to say so a bunch of amateur modders don't you think? I know of what you speak, I know not how to check/measure it. And I can't imagine many do.
Also, I'd love to assume companies like FSWerks at least have some level of due diligence in this regard, and wouldn't be selling a destructive product.
