I've seen that MAF cap get reached on an N/A 6G74 before... you'll see it with 3 psi on a suck-through setup.
And any blow-through setup on a Karman vortex MAF is just ridiculous. You'll soon discover that if you ever run more than a few PSI of boost... think of how you're 1.) pressurizing the plastic housing itself 2.) pressurizing the barometric pressure sensor (which has a reading limit within the ECU of a few hundred ft below sea level IIRC), and 3.) registering airflow of pressurized air (meaning the airflow reading will always be lower than the actual mass airflow into the engine, meaning inaccurate tuning). I'm not calling you dumb, I'm calling your blow-through MAF setup dumb.
