Product Description:

The Duramaximizer was specifically designed for 2001 through 2006 Duramax diesel engines and provides up to 100 horsepower and 180 ft.-lbs. of torque with the turn of an “infinitely” adjustable knob, load sensing for smoke-free operation and maintenance of exhaust gas temperatures (EGTs) within manufacturer tolerances and decreases unnecessary transmission downshifting while towing.

With a sophisticated processor sealed in a billet aluminum cover, the Duramaximizer provides maximum power without altering the factory PCM, internal components or exhaust system.

For more horsepower, use the Duramaximizer in conjunction with a Xcelerator programmer.

Includes dash panel insert and Duramaximizer adjustable power knob.

When ordering, please specify whether you have factory fog lights or a passenger air bag switch. This information is used to select the control knob location kit.

Note: “Legal in California only for racing vehicles which may never be used upon a highway.”
