Hypertech Max Energy for Chevy GMC 6.6L Duramax - The Best Handheld Performance Tuner!

Hypertech Max Energy Power Programmer for Chevy GMC 6.6L Duramax extracts every bit of energy possible out of every molecule of fuel giving you more miles at part-throttle and and more power at wide-open throttle. In order to increase engine efficiency, horsepower and torque, Hypertech engineers first optimize the spark and fuel curves point by point over the entire rpm band. In addition, Hypertech’s exclusive Transmission/Converter Programs in every power programmer further increase fuel mileage by lowering automatic transmission shift points and locking the torque converter at lower speeds for less torque converter slippage

With the additional power and optimized transmission functions, Chevy or GMC 6.6L Duramax drivers use less fuel to accelerate and maintain cruising speeds without the torque converter un-locking and transmission down-shifting to a lower gear. The results are maximum power and fuel mileage.

The Hypertech Max Energy for Chevy GMC 6.6L Duramax has the capability to not only read and clear diagnostic trouble codes, but also provides an easy to understand explanation of what the code means. Just another example of Hypertech's philosophy of giving drivers features and power they can use, all in a package that is 50 state legal.
