Re: HEI Tach adapter for Sun Super Tach?

When I first installed the tach last week it was "jerky" and would ratchet up with the RPMs or stop and hold at a certain spot. Not a smooth movement. Over a few days of driving it seems to have smoothed out. The filter arrives in a day or two and I will update as to what if any improvement in accuracy occurs.
