All Duramax Modules

Dr. Performance Powerstroke Modules for Chevy/GMC trucks add power and torque by adjusting fuel pressure, which will cause the injector to increase fuel atomization efficiency.  As the atomization efficiency increases, so does your power and mileage.  You do not need to remove any of your emissions systems. The Duramax diesel modules are untraceable by ECU, which means the modules will not void your warranty and never go above stock safety parameters. You can safely trust that you’re getting the power and best fuel efficiency for your truck without causing any damage or black smoke emission. Our Chevy/GMC Duramax performance parts, including the Duramax Performance Module, give you better fuel mileage and more usable torque curve for towing, with no other modification necessary to take your truck to the next level.
