im getting my old unhacked maf back tommorow , my o2 reading on my a/f gauge arent circulating, it does when i first start driving the car but after a while it stays lean until i use boost then it goes to rich. But last night i was driving home from work and even at wot the gauge wasnt going rich, this is most likely my hacked maf since i dont have any type of fuel control?

Try the unhacked MAS, but it could be simply that your O2 sensor is dead and might need replacing.

just replaced the os sensor before i only got an o2 reading under wot now i get one while driving normmal but after a while of driving the gauge just reads lean and doesnt fluctuate stays red
