hello kind peeps of my fellow thunderchicken lovers club. I just had a new engine put in my 5speed 89 sc. Im getting plenty of vac( around 20+ ) but no boost. with wot The gague goes to 0. I was checking the bypass valve and it is not moving. In fact it is hard to move. IF I move it by hand and rev it I get a + boost reading. does this mean I need to replace the bypass valve? I tried to search in the threads but could not find this prob. Much thanks ahead of time for your input. It does close slowly!!! when I shut it off
