Can you take a pic of the top of the supercharger? If the volute isn't rotated enough then I can see how the pipe would come up short.
And yeah you should not be going negative in higher rpm bands. But with a new belt and the same setup as most I'm not sure how you are getting that amount of slip. I can see how it would stop building boost but loosing that much up top is strange.
