Probably not. 1500/1600 Vulcans only run 25 deg ign advance and that has to be pulled back with the big bore kit and cams. It's indicative of a really good burn in the combustion chamber with the stock ignition. An appreciable improvement is unlikely.Z, just got to thinking maybe a Multi Spark Discharge would improve performance and mileage at a reasonable cost. I am not interested in re-mapping.
