Boost Gauge Nissan 3litre GU IV????

Are you talking 'Boost Gauge' or 'Vacuum Gauge'

Voxson,
I’ve searched high and low and can’t find a plug on the manifold anywhere. It’s a simple operation on the 3.0l Navara because they don’t have an intercooler, the boost controller is remotely fitted and it’s simply a case of tapping into the tubing with a T-piece.
The patrols intercooler mounted boost sensor doesn’t allow this.
Ideally the boost gauge should be plumbed into the manifold, because unlike conventional diesels, the patrol does have a throttle body and under certain conditions the boost will vary between the turbo/intercooler and manifold.
I’m not too keen to pull my manifold off to drill and tap it, so I’m going to drill and braze a fitting into the steel bend that the intercooler hoses clamp onto at the front. This will tell me what boost is in the intercooler, which although not ideal, still gives me some idea of what’s going on. The only other thing with doing it this way is that it will show higher boost levels when the accelerator is suddenly released which won’t be true and accurate to what is in the manifold.

Is there a problem putting a "TEE" in the line from the turbo to the wastegate actuator. It's not on the manifold side but does that really matter? It would measure boost at the turbo rather than at the manifold.
