Update  looked online for the manual for my tachometer apparently there's a small switch inside the housing that is adjusted for the number of cylinders for your application it was set for a 4 cylinder lol . Funny thing is all auto meter tachs are preset from the factory for 8 so that means someone went in a changed it later. Thought i would let everyone know if they are having an issue with theirs.
