pull the line off and its going to spike way past 25psi.
w/ no boost source being sent to it, there is no boost to open the WG diaphram to bleed the boost off...so it just builds up in your manifold and makes you spike like crazy.
at this point only 2 things i can think of if you arent leaking is possible WG or a bad rebuild maybe
and you said the WG isnt leaking out of the vband...?
