A/M boost gauge flicker

[DevenWood]

I'm sure this question has been asked before, but I could not find anything close while searching.

The needle on my new Cobalt boost gauge flickers at higher boost, 30-50 psi. Any ideas?



P. S. Had to ditch the Dakota Digitals. Nothing but problems. Good costomer service though.

Devon, here's the other posts about the needle shaking, fluttering or whatever we should call it. Mine does it also. It may be because the line is connected right at the intake port on the manifold.
