    Default Installing an aftermarket tacho

    Hi,
    I have just ahd a Speco Tacho installed in my commodore, and it doesn't give a correct reading, can anyone help, the auto electrician couldn't help. I rang the company, they blamed the installation, and the auto electrician, did everything as per the instructions. When running at 2500 rpm, on the dash tacho, the speco tacho reads only 1900rpm. It was wired into the tacho feed wire behind the dash, is this correct???, what can be done to make it work!!
    HELP!!!
