Air fuel ratio question

Been running this tune for a good couple months nothing is wrong but did noticed at WOT my A/F ratio is in the high elevens. I'm I running rich? Usually at idle or cruising half open throttle it will stay around the high 12s. Here's a quick vid of WOT.

That is very rich. One of the problems with the one size fits all canned tuners and why they don't shine a light to Uprev and the things we can do with a custom tune.
