I have a bothersome question for everyone if y'all can help;

So since installing everything I was monitoring boost pressure last night heading home and this morning heading back into work and I noticed at max I was only hitting 5-8lbs.

I went about 40% throttle at one point and at most I might've hit 8lbs. Is this normal? Am I losing something? Maybe a bad seal or a loss within the turbo?

I don't know what's normal for this, last diesel I owned was a 91 and that truck would give you 44lbs if you gave it a dirty look and talked nice to it.

I feel like I messed something up or something isn't right.
