Product Description 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. 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. For vehicles that come from the factory capable of using regular octane fuel, two (2) optimized tuning programs are provided: one for premium, and the other for regular. In most cases, Hypertech’s exclusive Power Tuning for regular octane provides excellent power gains, almost as much power as premium octane. Only one (1) Power Tuning program is provided for vehicles that were designed from the factory to use only premium fuel.
