Your cart is empty.Compatible with 2021-2024 GM SUV and 2022.5-2024 GM 1500 Truck Refresh V8 Models; The DFM (Dynamic Fuel Management) Module is compatible with late model GM Refresh trucks and SUV's. This innovative device is the first in the market to provide a solution for disabling the dynamic fuel management system in these vehicles. By installing the DMF Module, users can effectively override the vehicle's built-in cylinder management system, allowing the engine to run on all cylinders, all the time! This leads to a better driving experience, and better long term engine reliability. The 5.3L and 6.2L V8 engines in these vehicles offer excellent power and fuel mileage, but have been plagued by negative side effects from the factory DFM systems for years. Excessive engine oil usage, fouled spark plugs, failed lifters and valve train components and even complete engine failure. Don't let your brand new V8 leave you stranded on the side of the road or stuck with an expensive repair bill. Eliminate that worry from life and install the all-new DFM Module today! This device is a true dual threat eliminating the most frustrating features your brand new truck or SUV's came equipped with, DFM and Engine Auto Start/Stop. By simply plugging this device on to your ECM, both systems will remain inactive at all times, leaving you with the peace of mind your engine will run more consistently without issues or interruption. Just hop in and drive without the worry of cylinders cutting off leaving you powerless or the engine shutting off at every stop sign, creating a hesitation on take-off or killing power to your in-cabin luxuries like A/C and rear entertainment systems.;

I'm so happy they've finally released a module that's compatible with a Chevy Silverado 1500 that has been refreshed (2022.5 and up)!!! I ordered a different module previously that was incompatible with my truck and had to sit on my hands and wait due to the updated software in the refreshed chevys. While this isn't as easy to install as the plug and play OBDII module, the installation wasn't that complicated. Once installed, it works perfectly! No more auto start-stop, and the active fuel management garbage is gone! Loving this module.

This did exactly what it’s supposed to do and easy to install. This will save your transmission and engine.

A little awkward to install and lost almost 2 mpg.

Great product. But be aware that when you install it the module unit is much thicker and the felt wheel well liner does not cover it. Therefore it is suseptable to water, mud, and rocks. I cut a little extra felt to help cover it but its a concern.

The module was easy to install and defeats DFM and Start-Stop making the truck more enjoyable to drive and more dependable.

Does exactly what it's supposed to and was an easy 10 minute install on my '25 sierra 1500 with 6.2l V8.
