Max Energy Tuning extracts every bit of energy possible out of every molecule of fuel giving you more miles at part-throttle 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. 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.
