2011 Corvette LS3 (Gen 4) with Magnuson 'Heartbeat' supercharger

I just started using the HP Tuners and did a log file with the VMC Scanner today.
I know that my max boost from this supercharger is about 7 PSI, but today, when logging "Intake Manifold Absolute Pressure (SAE)" it showed 22 PSI of manifold pressure when at WOT @ 6,200 RPM.
Now, I know for a fact that this supercharger don't make anywhere near 22 PSI of boost.
Any idea as to what is going on here ?
Thanks,
Ron
