It is possible that the actuator rod is holding it open which is causing the surge since it in't solid like the set-screw and is flexing causing the big by-pass blade inside the blower to occilate open and close. It is only held on with two hex head screws so it should be an easy fix. It would also expalin why your power doesn't keep climbing like it should with a blower. Let us know what you find. Not saying anything one way or another, but I am sure Vengence doesn't hardly ever change these out so who is to say the guy who changed it just didn't un-bolt one and just throw the other one on. It looks simple enough so how can you screw it up, right???

OH. I can screw anything up. lol
But, I actually noticed exactly what you are talking about. That the set screw and metal flat part on the plunger arm will have a small gap from time to time. Next time it surges I'll get right out and look and play with it. As I type this it is touching like it should.
BUT
When the car is idling with not boost that arm is open all the way. It only closes at boost. The manifold vacuum holds that actuator up away from the set screw under vacuum.
Unless I missunderstand you.

Ideally I"d create boost WITH bigger headers for even more power at the same boost with a less compression ratio.
But boost is boost. Displacement changes will always effect power.
