Ideally, you would be somewhere in the upper 11's to be safe and still make strong power. With the meth you might be able to go even leaner, into the low 12's, but it depends on how much more power the car is making. Going from an 11.8 to a 12.2 and only gaining 5whp is not worth it from a safety standpoint IMO.
On nitrous, I personally like to see the car get a bit richer, .2-.3 lower AFR's on bottle than off. You have to adjust this through the nitrous jetting itself unless you have map switching capabilites and can run a nitrous map and a boost-only map. It's simple enough to go .01 larger on the fuel or .01 smaller on the nitrous side until you get the on bottle AFR within range.

Every car is different and depending on your exact setup, the car might make more or less power at a different AFR. I have no experience tuning these cars yet, and have no idea how they would react to boost+spray conditions.
