Factory Tach question

Hello guys, i have been searching and found answers to if the factory tach works or what you have to get it to work with a filter.
my problem is
I have a new HEI Distributor and installed a factory tach but when at 2000 RPM's it reads about 300 or so?
Any idea what I need to do?
