I'm second guessing the boost readings my self, I am using the omni 4 bar map sensor. I just looked at the peak number for Manifold Absolute Pressure (and confirmed it with Sebastian as well). But, actually going back in the logs and seeing when it hit that number, it hit .80 bar at around 6500 rpm, peaked at .88 bar at 7,100rpm, then actually dropped a bit to around .78 bar by redline (7,700 rpm).

I'm still new at forced induction, but correct me if I'm wrong but I don't think a centrifugal supercharger is supposed to hit peak boost before redline then drop off, I suppose that would potentially indicate a boost leak, however it's already making more boost than it should.

Here's the MAP sensor log for the pull:
