My car is on the original stock tune and the only changes are a Subaru catless uppipe and silicon IC hoses. After doing the upipe and hoses, I had to change the front O2 sensor due a code for heater malfunction in that sensor. I just cleaned the MAF in case that helped.
I did not log anything before changing the uppipe and IC hose, so I can't tell if that caused anything or if it has been like this for a while.
