H&S Performance is proud to announce the “OVERDRIVE” software. The H&S Performance Overdrive software is specifically tailored to H&S engine tuning software, but will also work well with any performance tuner on the market. The H&S Overdrive tuner is made to fit the Dodge Cummins 6.7L with the 68RFE transmission. The Overdrive tuner is expected to ship on July 1, 2010 at Thoroughbred Diesel.
