I have a Dynojet chassis Dyno in my shop and our experience is that you
will see a fall off on both sides of correct (optiumn) timing. Going
further past optiumn, you won't again find another better optiumn. A
good quality Air / fuel mixture meter will also help determine the best
air fuel ratio and timing.
