    The Tach don't turn more than 8000 in that year. Find a RXP Tach, is plug and play, and ualla you will get more rpms. Happen to me.

    Try this site for "Tiny-Tach. http://tinytach.com/tinytach/gasoline.php
    It seems like a while back there were a few people using these. I never really heard anything bad about them but maybe do a search related to this. Andy has got it. They changed from 03 to 04.
