12.6 is the edge of detontation on a turbocharged car. would shoot to tune for lower than that

Somewhere in the 11.5-12:1 range would be nice and safe.

Re: (bubs)

12:1 is about the ideal a/f for boost. It also depends on how much you are boosting. There are different ideal a/f's for different boost/power levels.
