Centrifugal supercharged 5.9 dakota makes low boost in high gear?

5.9 dakota vortech S-trim blower 11lb pulley setup. .210/.220 .512 lift cam with 110 LSA. And Mopar RT 2.02 heads.

Car makes full 11psi of boost in 1st and 2nd gear. Shifting into 3rd boost drops to 6ish??? And ideas as to what would cause this?

Thanks

Does it start building as RPM goes up in third or does it stay at 6 all the way to redline?
