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.

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.
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).
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
Automatic Transmission Adjustments
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
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.
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.
