most other failures would result in the boost gauge showing
some variation between idle and throttle positions other than
I would almost suspect your MAP (manifold input pressure)
sensor is not properly connected to the manifold...
pipe broke, large leak, etc.
On the outside chance, your MAP sensor is bad, but
this is highly unlikely based on all the list experience
I have seen so far.
Is there any way you can add a simple boost gauge
