Target AFR while stalling both dry or wet kit?

[v8s_are_slow]

My car is currently setup as a dry kit but can easily swap it over to a wet kit if need be. But either route, I'm not sure what the desired afr really needs to be while stalling with my secondary maps, and what is considered too lean? I'm trying to target 8.0 and hitting 11-11.6 on a 35 shot and about 12.5 when trying out a 75 shot. I want to be on a 100 shot for my 76mm. Just not sure of where I REALLY need to be with the afr's. Was thinking of swapping it to a wet to get the afr's exactly where I want them a little easier, wherever that needs to actually be though. Can't seem to find this answer.

Also, this is on a tank of E85 but when this is out I'm swapping to pump and meth injection. Although the nitrous will be on and meth coming on after that shuts down so just consider it on pump gas I suppose. Thanks!
