With that setup you will have to recirculate the BOV because that air is still metered air just like the stock setup. You are just switching to a better flowing MAS. There are no basic SAFC settings to run when switching to a 2g MAS because every car is different. You will need a logger to tune it accordingly and a wideband would help if you have one. From what I've read, a 2g MAS makes the car run leaner, so you would just need to do some logs and add or remove fuel accordingly to get rid of any knock that is present. I would start on the safe side and lean everything out a little and work your way leaner until you notice any knock since you will have 560's.

In case you haven't seen it yet, here are the instructions on how to wire up the 2g MAS.

Here is some tuning information for the SAFC.

No such thing as a base line set up!! You will need a 85 dollar logger to help you tune. You would still need to recirculate you bov. Your 1g bov would do fine. I used my 1g stock pipe! I works just a P.I.T.A to get on
