or Stage 2. The best way to determine the tune that will give you the best fuel economy is to try each

setting.

TRANSMISSION TUNING

Allison Transmissions (2001-2007 LB7, LLY, LBZ): The Allison transmission and controller on the

LB7, LLY, and LBZ GM diesel trucks is a very complicated piece of technology. The controller is

constantly monitoring the transmission performance and adjusts the operating pressures in small

increments to ensure the longevity of the transmission. The additional power of the Hypertech tuning

may cause the transmission to slip while the controller relearns the new torque output of the Hypertech

tune. The shifting will return to normal after several miles of normal driving. This may also occur when

changing between different stages of Hypertech tuning.

Allison Transmissions (2007-2015 LMM, LML): Each stage of Hypertech tuning for the LMM and

LML GM diesel trucks also adjusts the Allison transmission calibration with the necessary parameter

changes to handle the additional power. This results in a noticeable improvement in shifting feel and

drivability that matches the increase in power rather than relying on the transmission controller to slowly

adjust the settings.

Ford Automatic Transmissions (2006-2015 5R100/5R110W/6R140): Each stage of Hypertech tuning

for the Ford auto trans diesel trucks also adjusts the transmission calibration with the necessary

parameter changes to handle the additional power. This results in a noticeable improvement in shifting

feel and drivability that matches the increase in power, while protecting the transmission against

excessive slippage.

DIESEL PARTICULATE FILTER (DPF)

None of the Stages of Hypertech tuning will increase exhaust soot and therefore does not increase the

frequency of regenerations. Hypertech’s tunes are designed to work with all the factory emissions

equipment in place. Disabling or removing the DPF is illegal and enforced with hefty EPA fines.

AFTERMARKET PARTS (Gas and Diesels)

Hypertech tuning works well with popular bolt-on aftermarket parts. If you install an aftermarket air intake or

exhaust system, Hypertech’s Power Tuning will automatically adjust the engine control parameters to take

advantage of the fact that the engine is less restrictive. Any significant power adders, like superchargers,

turbochargers, nitrous, etc, would definitely require a custom tune. For reference, any racing parts that would

set a DTC with the stock tune would also set the same DTC with the Hypertech tunes.

COLD AIR INTAKE TUNING (Gas and Diesels)

Some vehicles require a custom tune when installing an aftermarket cold air intake. This is necessary to correct

the mass air flow (MAF) sensor readings and to take advantage of the increased airflow. Aftermarket air intakes

change the air velocity and the volume of air passing over the MAF sensor, due to the shape and size of the

ducting around the sensor, and even the type of air filter used. This can cause errors in the ECU calculations for

the quantity of air entering the engine. By correcting these errors, it ensures that the Hypertech tuning will

function properly with the air intake installed, and optimize the engine performance with this modification.

REV LIMITER

This option raises or lowers the maximum RPM limiter of the engine. The key to faster acceleration is to use

more of your engine’s horsepower. The Max Energy 2.0 lets you adjust your engine’s rpm limiter to improve

performance and driving fun. The stock computer is programmed to shut down the engine when it reaches the

redline. But if you have modified your vehicle to increase its high-speed performance, more rpm means more

power. When you shift gears at the stock rpm limit, the engine falls back to below the peak of its horsepower
