Can I get a Crazy Larry tune?


    Crazy Larry was a high horsepower tune we had available on select handheld tuners (Power Pups, and Triple Dogs).  Those tunes were only available for the older Cummins and Duramax vehicles.  We had to pull those tunes off the market since they were in violation of the Clean Air Act.  Those tuners have all been long discontinued and will not be added to any other devices.
