Max Energy™...The Best Handheld Performance Tuner On The Market!


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.

Max Energy Diesel Power
Programmer Features


Note: Adjustable features depend on year, make and model of vehicle. For a particular vehicle's features please use the "Search by Vehicle" at the top of this page.



Hypertech Power Tuning


The Max Energy Power Programmer offers three (3) stages of Power Tuning for Diesels. 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, gives the Max Energy Power Programmer the performance advantage.


Speedometer Calibrator


If you’ve installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Max Energy allows you to re-program for correct speedometer and odometer readings, as well as correct part-throttle shifting. The vehicle’s computer calculates your vehicle’s speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is going. As a result, the automatic transmission may not shift correctly and the speedometer readings will not be accurate (as required by law).


Top-Speed Limiter


Automobile manufacturers limit a vehicle’s top-speed to match the speed rating of the factory-installed tires. If you have installed tires that have a different speed rating, the Max Energy allows you to raise or lower the vehicle’s top-speed limiter to match the speed rating of the newly installed tires. A tire’s speed rating for maximum safe speed under perfect conditions is marked on its sidewall. Always obey all traffic laws when driving and only use this feature for off-highway competition in sanctioned events.


Automatic Transmission Adjustments


Shift Firmness

Increase shift firmness to maximize performance or when towing, to reduce clutch slippage and transmission oil temperatures. That means longer transmission life. However, this feature must not be used If you have installed an aftermarket shift kit.


Shift Points

The Max Energy allows you to raise or lower the shift points in 100 RPM increments for maximum performance, quicker acceleration, and better 1/4-mile times. With the Max Energy Power Programmer, you have the ability to customize the shift points for every gear. Optimizing each shift point can definitely improve performance.


Read & Clear Diagnostic Trouble Codes(DTCs)


If you get a “check engine” light or “service needed” message, the Max Energy will allow you to read the code and gives you the ability to clear the code and turn the “check engine” light off. You can then make the necessary repairs to prevent the light from coming back on.


Return To Stock Or Change Option Settings


Hypertech’s Max Energy downloads and saves the stock tuning program, then uploads your customized Power Tuning program. Before taking your vehicle into a dealership for service, always return the vehicle’s computer back to the factory programming. Once you have the vehicle back from the dealership, reinstall the Max Energy Power Programming as before. The Max Energy can only be used on one (1) vehicle at a time, so if you sell your vehicle or want to use it on a friend’s vehicle, simply return your vehicle to the stock tuning program and you may then use the programmer on another vehicle that is covered in the same part number.


Internet Updateable


The Max Energy Power Programmer comes with a USB cable and a CD containing software to enable quick updates over the internet. If your vehicle has a new calibration not available when your Max Energy Power Programmer was manufactured, it is possible that you will see a “Cal not found” message on the Max Energy screen. If this occurs, you can simply update your Max Energy with the correct new calibration via the internet. Simply connect the Max Energy (using the provided USB cord) to your computer and go to www.hypertech.com. Then click on the Support button to get update downloads. You can also get the update downloads using the CD which also contains an installation video and a printable version of the instruction manual.
