Have a look for any vacuum hose that might have a kink in it, my car had boost problems, and it just turned out to be the vacuum hose coming off the n75 valve, causing it to stop the wastegate from working.

Scan it for codes. This should at least tell you where to start looking.

Standard (unmapped) boost is only about 5 psi or thereabouts, so you are not far off.

Itll be a block or cracked pipe somewhere, check under the inlet manifold maze of pipes under there

Are you getting no boost at all or are you getting very low boost. Check the bolts holding the turbo on the manifold
