Here are the codes it is throwing. This is a fresh Stage 2 93 Octane flash, all codes cleared beforehand (I did all of this last night), and with the STOCK intake and STOCK air filter. I drove a 40 mile commute today. This is what CELs are on.



The Air Mass code seems to be the most concerning. Somehow I don't feel that the other codes are real? Some input here would be nice.

I already cleaned the MAF sensor already during a different troubleshooting process.

Good luck!
I didn't. I am no expert! I did note in my original post I noticed that the ignition timing was off in certain areas, but I didn't know what to conclude from it.
