I don't have any AFR data yet, but I am bringing it back to my shop at some point soon to address a few remaining items (minor electrical and suspension). My shop has a nice mustang dyno so we can check the vitals including AFRs.

It looks like the shop has done a nice job setting your car up, and would undoubtedly been setting AFRs.
Just that things can get out of whack for a number of reasons. You don't want your AFRs straying lean when running high boost and rpms. They tend to lean out at the top end - depending on the health of your fuel system. Also they can get pig rich - which you don't need from a performance aspect or engine wear. So it is very useful to have a permanent AFR set up. You can do your own tuning at that point too.
