The Range Technology AFM/DFM Disabler Device Modules let you make the most out of your V6 or V8 GM vehicle by allowing it to run in full-cylinder mode at all times. These modules feature advanced technology that efficiently disables Active or Dynamic Fuel Management without reprogramming the factory ECU. This means you get optimal power benefits without factory warranty concerns. These modules eliminate shuddering while the engine switches between running on half or all cylinders, plus problematic valve lifters will no longer constantly activate and deactivate to help minimize the need for costly repairs. With all cylinders firing, you can expect better power levels at light throttle.

Established in 2010, Range Technology manufactures high-quality solutions that aim to improve the efficacy of Active Fuel Management systems in GM cars and trucks. With a team of knowledgeable and passionate electronics engineers, the company is known for providing cost-efficient products that won't re-flash the factory ECU. All these products undergo hours of precise engineering and thousands of miles of real-world testing.

Range Technology has consistently evolved with time, offering a plethora of Active Fuel Management, Multi Displacement System, and Auto Start/Stop products to enhance late model GM, Chrysler, and Ford applications. Their products integrate premium-quality materials and advanced technology to guarantee refined solutions meticulously customized to suit your specific driving needs. As an industry leader, Range Technology offers precision-engineered products that are second to none in functionality as well as performance. Additionally, these top-of-the-market products can be easily installed, without needing any complex tools or procedures.
