if you run one of our CDI+ boxes you will see similar gains to a twin spark setup, especially on the early engines due to the exact reason chris_seven gave above.
It is a true multispark, up to 10K RPM, unlike MSD which reverts to a single spark at 3400 RPM on a six cylinder engine. The second spark further ignites the fuel as it swirls in the chamber producing more power.
Steve W, have you dynoed that box we sent yet???
