I bought a Isspro boost gauge (Foreign built) about 6-7 months ago. after a couple of weeks it started sticking at zero boost and it takes 10lbs or so to get it moving. or a good smack, after that you can monitor the lower boost levels. . I figured it would loosen up in time but it still sticks. I tried hooking the line up to 35lbs and just exercising it but it still sticks. . Anyone have a idea to get it moving proper without pulling my pillar mount?.....
