MAF Sensor 1 Bar or need 2 Bar

xxxxxx

The E-Force kit should have come with a 3 bar MAP sensor. The MAF (Mass Air Flow) sensor doesn't care about boost level, just airflow. My E-Force came with a blade type MAF sensor that can read up to 15000 Hz. If you're near sea level, subtract roughly 14.5 PSI from the MAP reading to determine the boost level. We need to know what OS and ECU you have before we can tell you if you need to scale MAF readings.
