You should be in the ballpark of 20 psi.
There are many factors in low boost. You need to check for boost leaks, major up pipe leaks, stuck ebpv. When I had a low boost condition it was because my ebpv had chucked the clip and the butterfly was free to move.
How does your turbo sound? Nice clean whine or is it more like an air hose in your exhaust
