i thought someone made a snubber for this problem , but could not find one.

what brand gage is having the fluctations. do they all read boost and vaccum? i know that was intended for a gas motor. there might be a difference internally (snubber).

 

i have mostly heard reports on here of the autometer's having the problem

 

what set up do you have?

 

ihave no set-up. well i have a test gauge installed and i get no flutter from it. its a gauge from an oil pressure tester

 

I have the exact guage that he showed in the picture and it looks just like that when I hammer down on it. Although I dont quite get 25-30psi though!!
