The Hypertech Max Energy tuner 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.

For gas vehicles, higher compression ratio engines and engines with superchargers or turbo chargers were designed to use only premium octane, so only one Power Tuning program for premium octane is provided. But, if your car or truck came from the factory capable of using more economical regular octane, then two 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. If you are using premium octane, and you want all-out, maximum power, then select premium octane Power Tuning.

For diesel vehicles, three stages of Power Tuning are available. Even the highest power level, Stage 3, maintains safe EGTs while towing the maximum weight specified by the vehicle's manufacturer. No other tuner offers this level of power for towing. Hypertech’s low EGTs, proper transmission shifting and superior tuning that doesn’t require de-fueling, giving the Max Energy Power Programmer the performance advantage.

In addition, Hypertech Max Energy tuners allow you to adjust:  speedometer calibration (if you’ve changed gears or tire sizes), top-speed limiter, automatic transmission shift firmness and shift points, engine RPM rev-limiter, cooling fan on-off temperatures, and much more.  The results are maximum power and fuel mileage!
