  • Are you refering to the Stage III upgrade? My guess is that you are. The Stage III is raised compression that will run perfectly on premium pump gas. A camshaft change along with valve springs and titanium retainers. Programmable ignition system, carb upgrade and dyno tune.

    A Stage II upgrade would include the carb upgrade along with a programmable ignition.
