How quickly/smoothly does it hit 8psi? Does the needle bounce any or is it solid at 8psi?

Then you most certainly have a boost leak and it sounds like a fairly sizable one. I'm betting your wastegate has never even opened since it hasn't needed to.
How are you checking for leaks?
If you pressurize your intercooler piping and determine no leaks there, then you have to check the turbo manifold gaskets and also the wastegate gaskets.

For reference, my GT2871r hits 7psi by 4K rpm (no boost controller yet). My old IHI hit 12psi by 4K rpm.

Found the problem. Was the valve seat to the wastegate. Put it in and made 16psi. Blew some IC piping off lol. Then popped the hood and saw lil smoke coming from the under side of the exhaust side of the turbo
