Didn't you already change your injectors? Do you still have those extra ones sitting in your garage you could use to further test things out?
Injectors were replaced about a year ago under the recall. I ordered some new ones today. I'll take some more logs in the meantime.

I just took some logs and oddly enough, the AFRs look nice and smooth on the Cobb "stock-like" map but there a lot of overboost-induced throttle closures. I'm guessing the reason is because it's not tweaked for the increased VE of a FBO car. I'll try the more aggressive maps tomorrow.

Sorry, forgot to log boost on these and sorry for the messy plot (RPM is dark blue and on secondary axis).
