MAF Scale for Jackson Racing Superchager - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I have been helping my friends tune his BRZ. The m/s scale seems low to me. Much lower then when I tuned my Vortech. Can someone confirm that the m/s numbers are much lower on the Jackson Racing Kit.

It's a different intake isn't it? You'd expect MAF values to be different.

I have custom scaled a bunch of NA intakes but this is way lower then anything I have seen. Most tend to be higher numbers flowing more air but this is the first time I have seen lower. I just wanted to check my work with someone else to be sure there wasn't a boost leak even though the car has been tested. If this is true I can see why the Jackson racing kits have problems with maxing out the MAF sensors, its lower then a stock NA car. I might have to try to do a hybread speed density setup for my friend.
