You want to stay as close as possible to 14,7 as long as you got no detonation or overheating exhaust valves.
Then your tuner will decrease AFR just enough to protect the engine. You don't want the lowest possible AFR, because you will loose at lot of gas and quite a bit of power.

Perfect chart. Yes idle was was sitting at around 14.7.
At WOT above 7k I hit 10.2 and I thought that was really rich.
I'm going to ask if they can keep AF ratio between the suggested 11-12. Thanks for the replies!
