Default

factory a/f at idle is around 15.3, sounds like you are fine you want it stay under 12.5 boosted and around 11.5 in the higher rpms when you are on it. do a WOT and check the log. if cipher logs knock count you can check that too. most of the startup canned tunes are fine they are usually rich enough to keep you out of trouble.

Edit: the 12.5 and 11.5 afr's may be low when you get it tuned they can push it leaner so long as you don't knock to make more power
