I don't think the AFC has any place here. If you're using it to tune the nitrous shot, how are you only using it when the nitrous is activated? Wouldn't you be running nitrous corrected fueling at all times that way? If I misunderstand your setup please clarify.
You certainly need to pull some timing, I usually start with 2 degrees retard and try up to 4. Nitrous in most cases makes more power with a little less timing regardless of the knock threshold. Either way 2 is a good place to be if you don't have more options and time to test.
As far as figuring and getting the custom chip made... Is there any reliable way to translate afc correction factors over to the chip burner? Ideally one would have the chip burned after test runs (with a romulator) on the dyno, but I know this might not be possible. So is the fueling going to be a flip chip also (I don't even know if this is possible for you guys yet)? Otherwise you're no closer to getting it right that route.
As I said, if I missed something, please clarify.
