GTR boost gauge reading zero

[Gav]

The factory boost gauge in my r32 GTR stays on 0. No vacuum at idle/cruise, no boost under load.

Needle goes back to bottom of dial when power off, then to 0 when power on or running.

I'm guessing that the MAP sensor is either buggered or there is a break in the wire. Where is the sensor located?

Look on the firewall on the drivers side, there should be a little black box (about 10cm across) with a vacuum hose going into it and a few wires, check that the hose is still connected properly first.

This is where its located on the GTSt so im guessing its the same for the GTR

Red17 - Correctumundo!

The hose has popped off - but from where?

Can someone with a GTR have a look where the vacuum/boost hose plugs into the plenum?
