    MAF Sensor 1 Bar or need 2 Bar

    Hi, I have a few days before i can get back onto logging to see if I peg the MAF output at redline.
    This is all new to me but working on a 2012 Escalade 6.2 that has had a Edelbrock G Force blower added.
    I'm assuming MAF is stock.
    Getting some nice MAF tune but looking at what I have so far, appreciate any experience to get your feed back on my numbers.
    At idle around 3000hZ and 9.5g/s
    at 5765rpm is 10,349 Hz and 387.2 g/s
    are we getting near max? Will max the engine at 6000rpm.

    Side note: at this 5765rpm manifold pressure shows 108kpa (15.67psi) \. I know it cant be making that much boost - so atmospheric pressure comes into play

    Also Ambient temp shows 54C (SAE) - the blower upset the sensor placement?

    Thanks for any help

    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.
