Max Energy Tuning 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, our 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 to further increase fuel mileage by lowering automatic transmission shift points and locking the torque converter at lower speeds to average less... • engine revs • intake strokes • friction and pumping losses and • fuel wasting torque converter slippage. With the additional power and optimized transmission functions, 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.Max Energy...The Best Hand held Performance Tuner On The Market! #32006
