so i think i have some sort of short in my tach. when i'm stopped, or going & shifting through gears it acts fine, but when i'm on the highway & somewhat maintaining a constant speed, it likes to jump from like 3 or 4k up to 5 or 6 ... like it twitches really quickly back & forth.

is it worth ripping it apart to find the short? would a new cluster fix this problem or could it be beyond the actual cluster?

or should i just suck it up & live with it ??
