"Parallax error" is caused when not viewing something from dead in front. It can cause the needles on gauges to under-, or over-read.
It is more prevalent when the needle is a greater distance off the gauge face. A gauge whose needle TOUCHED the face, ie: lay on it, would exhibit no parallax error.
To experience parallax for yourself, set up two pencils, for example, so as when you view them, one is behind the other. A distance of abour 5cm between them will do.
Now, wiothout moving the pencils, simply move your head to one side, or the other. See how the pencils now appear to separate? That's parallax error.

Well the result, it looks like I had plumed the gauge into the wrong pipe (after reading some other threads) I had used the one from the actuator... the result no different
foot down 4th gear over 5500rpm it just manages 0.6 the only difference now is it reads negative pressure which it wasnt before
I managed to evade the cameras and dodge the points.....

As the boost guage measures vacuum and boost it can be "T"d on to any offtake from the inlet manifold so that it has direct access to the inlet manifold and not after other boost sourcing apparatus eg. WG actuator.
As long as the boost guage pipe can see directly in to the inlet manifold through a "T" feeding something else that is satisfactory.
As regards your lack of boost problem it may be an issue with your plumbing but it needs someone that knows what they are doing to look at it because giving written advice is unlikely to be successful.
