Re: Hopefully this Board fixes my Tach problem
My Burban has a factory tachometer in it and it has always read high at idle by about 300 rpm and 800 or so at 55 mph. Last week I replaced the HEI with a Pertronix set up and the unexpected benefit has been the tachometer reads about 75 rpm low at idle and 300 at 55 mph.
I am guessing the rest of the error is in the 50 year old tach.
