I am running lean with stock injectors and ECU. Did a boost leak check and sealed up the leaks but low fuel trim still showed lean. The MAF was showing 25Hz to 31Hz at idle. Seemed a little low and cleaning it didn't help. I also noticed that sometimes it would go to 0Hz while it was idling but hasn't done it recently. I tried unplugging the MAF sensor and the throttle response improved with no knocking and I confirmed it was running rich so I don't suspect the injectors. I also checked the fuel pressure and it was to spec. I am going to do another boost leak test soon. Should I continue to suspect a bad MAF sensor?
Also, is it possible to use a 2G Mass Airflow Sensor with stock ECU and Injectors without using an Air Fuel Controller?
