H&S Performance is proud to announce the "OVERDRIVE" software. A finely tuned engine is worthless if that power cannot be transferred to the ground. In order to meet the high horsepower and torque output of the 6.7 Cummins engine, we have modified the transmission tuning software to better "put the power to the ground". The H&S Overdrive software is specifically tailored to H&S engine tuning software, and will ensure that you get the best performance and reliability out of your transmission.
