What the hell's wrong with you? Bov problem? Belt slip? As shown in the video, the boost leak at 6400 rpm. At this time, the boost is 13.5 psi. however,When the boost rises to 7300 rpm, it is 14.5 psi.

I’m not too sure what the exact question is here, but it makes sense for you to see an increase in boost from 6400 to 7300 rpm. It won’t be consistent throughout the rev range.

As to how you’re making 14.5 psi with a 9 psi pulley, I’m not sure…
