Max Boost on this garrett turbo??? 4.5lbs

i’m currently running a Garrett Airesearch TA0301 turbo Mercedes 300D SDT TD on my integra but the max boost is only at 4 or 5lbs. I’ve tried turning the boost up but the boost controller doesn’t seem to do anything to it…i dont have a external wastegate on it yet and i don’t think it has a internal wastegate…because the exhaust side for the wastegate is blocked off…but it has an acutuator though…only thing left i have to do is get my turbonetics wastegate put on the manifold and see if it makes any difference i was wondering if anyone experience with this turbo or have any info on this…thanks
