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.

Tune- 93 octane, extreme throttle, WOT off, 2+ timing advance, speed set to 180.
I can't afford uprev at the moment so is their anything I do to fix it. Maybe adjust the timing? Take off the 2+?
I just changed the wideband setting from sensor B to sensor A and this is what the A/F is showing. Is this better?
