Where Are They In Sturgis? Zipper’s Performance And Thundermax.

Both Zipper’s Performance Products and Thunder Heart Performance Products crews will be located at Black Hills Harley-Davidson from August 9th to 14th. The 2 companies work together to develop the ThunderMax System. Representatives from both companies will be available to discuss the ThunderMax system and will be selling and installing it. They will, also, be available to to answer all of your questions about EFI performance, map units and help customers with their maps on pre-existing ThunderMax installs.

Something to know about the Black Hills. Conditions vary an extraordinary amount. You will see corrected altitude numbers vary from 4300 to 6500 feet in the same day, creating rich conditions that are unnecessary and waste fuel.  ThunderMax will correct these rich conditions while you ride, increasing your motor’s efficiency while keeping it cool. ThunderMax is one of the most cost-effective ways of automatically keeping your bike properly tuned, regardless of changes in riding conditions.

You can order your ThunderMax now and have it professionally installed by the ThunderMax team during the Sturgis Motorcycle Rally. To contact us and schedule an installation appointment, please call: 410-579-2828 or email Zippers@ZippersPerformance.com

    I have a Thundermax on my 2009 FLHTC and am very happy with it.
    It made the 96 CI engine run like it is suppose to
    I had it installed during bike week in Daytona Beach and have over 8000 miles on the motorcycle since it has been installed.
    I ride all over the country covering motorcycle events including to Texas 3 days after it was installed and last weekend to West Virgina.
    Next week I ride to Sturgis and I am convinced that it will continue to perform well there and back.
