Boost Gauge plumbing
I`ve got a boost gauge fitted and it does not work correctly. It will not boost past 0psi. I`ve had then sender changed. But it still has the same problem. It is the gauge or where i`ve got it plumbed in. If you look in the pics of my engine bay it is the blue pipe connected onto the manifold on the left. It`s a 2003 WRX by the way. Should it be plumbed in on the right hand side coming of the dump valve or does it make much difference.

Where you have looks to be fine, although I cant see which pipe it is clearly.
Is it as shown here
Scoobypedia | Trusted knowledge for everything Subaru | Boost Gauge browse
There appears to be 2 mounting points which work, one being where you have it, the other being on the vacuum tube leading to the dumpvalve.
I went for the dumpvalve fit myself and it works fine. You could try that fit
easily enough, but I'd recommend not cutting the OE pipe that's on the dumpvalve at the moment. Use an additional short section of 6mm fuel pipe slide that onto the dumpvalve, the T piece into that and the other straight section of the T piece into the OE pipe. Then you can put the OE pipe back if needed when you've tried it.

If you need a 6mm -> 3mm T piece to fit it there lma motorsport will supply em if you give them a ring.

Plumbing it via the dumpvalve is a usual place it can cause the dumpvalve to misbehave
in some circumstances. I found that plumbing into the pipe directly from the mainfold works better. If you look at the manifold in the centre there is a round hole, to its left and slightly down 1/2 inches is a pipe that has a rubber hose on it, take pipe off (its a push fit) t-piece in and refit job done. My defi's where fitted wrongly and with ethanrob's guideance I did this

I couldnt
see the pics yesterday I was in work
but thats exactly how mine is plumbed in and I have now probs. As a rule it should read minus when not accelerating or under load then goes above zero when giving it some right foot
Check for leaks even to the point of putting clips on the joints if you have just push fitted them then its down to the boost reader or the gauge depending on what type you have.
Good luck
