Been having a few issues with my new setup, namely lack of boost.
Having rectified a couple of other minor issues it still doesn't boost more than 19psi (That's indicated on the in car gauge and also the SECS monitor).

So last night I was pissed off and decided to have a look at it again to see what the issue was, so after connecting the actuator to the compressor, seeing when it opened, and then taking it off the wastgate, i screwed it up about 4-5 turns knowing that should change it significantly, on connecting the compressor back up, it still read the same, so I took the car out for a blast out and it still doesn't boost any higher.

My powers of deduction tell me it's the actuator (-34), but it's a brand new unit supplied with a new turbo (2 months ago with very little use), so I'd like to be sure before I seek a replacement. Any other way I can test it?
