where u got the gauge plummed to on the engine??
one of the nipples on the intake manifold
can u not try a replacement gauge stood a the side of the bonnett?
Get a mechanical boost gauge and not a stepper motor gauge
yeah done that with this boost gauge and the needle moves a bit more but never leaves the green section on the gauge the video boost gauge is electric and this one is manual

hard to diagnose.. try remove the dump valve see if the problem is resolved then you know its somthing to do with your dump valve.
