speeds, which can lead to better fuel economy. With the optimization focused on the specific fuel octane

for each tune, you should see fuel mileage increases with all octane levels.

TOWING

All Hypertech tunes are optimized for towing. The Max Energy tuning is the only tuning on the market

that doesn’t have to offer limited power tunes for fuel economy or towing levels. Our tuning is safe for

hauling and towing the maximum weight designated by the vehicle’s manufacturer. We focus on

efficiency rather than a certain power output, so there are no towing restrictions other than the vehicle

manufacturer’s maximum allowed capacity.

E-85/FLEX FUEL VEHICLES

We recommend premium octane tuning for vehicles that are factory equipped to use E-85 fuel. The

improved engine tuning will increase the part-throttle efficiency and wide-open throttle performance

compared to the factory tuning.

Warning: Do not attempt to use the Hypertech premium fuel tunes with any fuel less than 91

octane. This could result in severe engine damage.

DIESEL ENGINE TUNING

The Max Energy 2.0 offers three (3) stages of Power Tuning for diesels. Even the highest power level, Stage 3,

maintains safe EGT’s while towing the maximum weight specified by the vehicle’s manufacturer. Our Stage 3

tuning offers the most powerful tune that maintains engine, turbo, and fuel system efficiency without

disregarding the integrity of other powertrain components. The Stage 2 and Stage 1 tuning offers the same level

of efficiency at more moderate power levels, which allows you to choose the tuning level that fits your driving

style. For instance, there may be times when you don’t want or need maximum power, like when the streets are

icy or wet.

TOWING

All Hypertech tunes are optimized for towing. The Max Energy tuning is the only tuning on the market

that doesn’t have to offer reduced power tunes for fuel economy or towing levels. Our tuning is safe for

hauling and towing the maximum weight designated by the vehicle’s manufacturer. We focus on

efficiency rather than a certain power output, so there are no towing restrictions other than the vehicle

manufacturer’s maximum allowed capacity.

The Stage 3 tune is safe to tow up to the vehicle’s maximum Gross Combined Weight Rating (GCWR).

If you are exceeding the vehicle’s GCWR, we recommend using the Stage 2 or Stage 1 tune.

PERFORMANCE

The Stage 3 tune is the most powerful tune available in the Max Energy 2.0. Go to Hypertech.com and

look up your vehicle to see the power gains for your specific vehicle. We make hundreds of dyno runs to

optimize every point over the entire RPM band while ensuring EGT’s remain in a safe range, and

keeping soot and smoke levels to a minimum.

FUEL ECONOMY

Fuel economy can vary based on driving conditions, vehicle loads, and driver habits. Most users that

tow heavy loads, 8,000 lbs or more, report that they get the best fuel economy using Stage 3. By

utilizing the maximum power, the vehicle uses less fuel to accelerate and maintain cruising speeds

without the torque converter un-locking, and the transmission downshifting to a lower gear. Most users

that do not tow, or sometimes tow light loads, report they get the best fuel mileage using either Stage 1
