I've increased the air intake into my rig by putting in some new MAF ends. The engine cranks, but dies almost immediately. I'm getting loud pings when it's running and have to keep the gas on. As far as I can tell, it's running really lean because the ECM isn't expecting all the extra airflow. Basically, I'm getting about a 30-35% increase in airflow with these new MAF ends. It's the same sensor, just with wider ports. Anyone know how I can advance the timing to allow for more fuel to meet the engine requirements now that I have more air moving through? For the record, if I put my stock MAF ends back on the sensor, it works fine.
