tacho accuracy

Just fit an after market tacho , typical style power from ignition ,earth to ground and feed from -side of coil. Problem its reading inacurrate out by 600 rpm at idle then at about 2500rpm it reads around 4000. This is where it gets confusing when I hook up a tacho/dwell meter at the same time as after market one the after market one reads more accurratly? Any ideas whats going on?
thanks in advance
