Unlock the full power of your Chevy or GM engine with the AFM/DFM Disabler Device. Designed for Chevy 5.3 Silverado and GM V8/V6 engines equipped with Active Fuel Management (AFM) or Dynamic Fuel Management (DFM), this device disables cylinder deactivation, allowing your engine to operate at full capacity at all times.

Key Features:

1. Disables AFM/DFM System:

   • The disabler device prevents the AFM or DFM system from deactivating engine cylinders, keeping your engine running on all cylinders for consistent power and performance.

2. Improved Engine Performance:

   • With all cylinders active, you’ll notice better throttle response, more power during acceleration, and smoother driving. Ideal for towing, off-roading, and maximizing engine performance.

3. Enhanced Engine Longevity:

   • By disabling the AFM/DFM system, the device helps reduce wear and tear on your engine caused by frequent cylinder deactivation, potentially lowering the risk of lifter failure and excessive oil consumption.

4. Plug-and-Play Installation:

   • Simply plug the device into your vehicle’s OBD-II port, and it starts working immediately—no tools, no reprogramming, and no need to modify your engine or ECU.

5. Compatible with Chevy and GM V8/V6 Engines:

   • Works with a wide range of GM vehicles, including Chevrolet Silverado, GMC Sierra, and other models equipped with AFM or DFM technology.

6. Maintains Fuel Economy:

   • Disabling AFM/DFM may slightly affect fuel economy, but many drivers find that the improved performance and driving experience outweigh the minimal impact on mileage.

7. Non-Permanent Modification:

   • The device can be easily removed at any time to restore the factory AFM/DFM functionality, making it a flexible and non-invasive upgrade.

Why Use the AFM/DFM Disabler?

Many drivers find the AFM/DFM systems disruptive, with uneven power delivery and potential engine issues over time. This disabler device ensures that your engine runs at its full potential, providing a smoother, more reliable driving experience without the downsides of cylinder deactivation.

Installation Instructions:

   • Find the OBD-II port under the dashboard, typically near the driver’s side footwell.

2. Plug in the Disabler Device:

   • Insert the disabler into the OBD-II port. It will automatically begin disabling the AFM/DFM system.

3. Start the Engine:

   • Once the device is plugged in, start your vehicle and enjoy full-cylinder operation immediately.

4. Optional Removal:
