If your filter is a type that requires oil sometimes that oil will get on the mass airflow sensor and skew the reading you can also try cleaning the mass airflow sensor with brake cleaner and Shop air

The MAF looks like it did the day I installed it, clean as a whistle. However, unplugging it made a huge difference. It smoothed out at idle immediately and I was able to drive the short distance back home with no popping and banging. Do you believe this is due to a bad sensor or could it still be something in the tune?

I'm going to make another run and record data with the MAF unplugged. With it plugged in, STFT's were 25% on B1 and 28.1% on B2. Timing looked stupid too.
