In recent years, automotive technology has advanced at an astonishing rate. One of the notable developments is the implementation of Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems by General Motors (GM) in their V6 and V8 engines.
While these systems are designed to enhance fuel efficiency and reduce emissions, they can have unintended consequences for vehicle performance and longevity. Enter the Southwest Speed New Range Technology AFM-DFM DISABLER, a device that promises to address these issues by disabling AFM and DFM functionality.

In this comprehensive review, we’ll take a closer look at this product, examining its pros and cons to help you decide if it’s the right solution for your GM vehicle.
Pros of this product
Improved Engine Performance
One of the standout benefits of using the Southwest Speed AFM-DFM DISABLER is the immediate improvement in engine performance. By deactivating AFM and DFM systems, the device ensures that all cylinders are active at all times.
This results in smoother acceleration, reduced throttle lag, and improved overall engine responsiveness. Users often report a noticeable increase in power and torque, making their vehicles more enjoyable to drive.
Enhanced Longevity
AFM and DFM systems can contribute to premature wear and tear on certain engine components, such as lifters and camshafts. Disabling these systems with the DISABLER can help extend the lifespan of your engine, potentially saving you from costly repairs down the road. This added longevity can make it a worthwhile investment for GM vehicle owners.
Fuel Economy Control
While AFM and DFM systems are designed to improve fuel efficiency, some drivers prefer to have more control over their vehicle’s fuel consumption. The Southwest Speed DISABLER allows you to deactivate these systems when needed, giving you the flexibility to prioritise performance over fuel economy during spirited driving or towing heavy loads.
Easy Installation
Installing the Southwest Speed AFM-DFM DISABLER is a straightforward process that can be completed by most DIY enthusiasts. The device plugs directly into your vehicle’s OBD-II port, requiring no special tools or technical expertise. The user-friendly design and included instructions make installation a hassle-free experience.
Compatibility
The DISABLER is compatible with a wide range of GM V6 and V8 motors, making it a versatile solution for many GM vehicles. This compatibility extends to various models and years, ensuring that a significant portion of GM vehicle owners can benefit from this product.
Potential Drawbacks
Warranty Concerns
One of the primary concerns when using a device like the Southwest Speed AFM-DFM DISABLER is the potential impact on your vehicle’s warranty. While the device itself doesn’t cause harm to your engine, some dealerships may void your warranty if they detect that the AFM and DFM systems have been tampered with. It’s essential to check with your dealership and fully understand the implications before installation.
Limited Fuel Savings
While the DISABLER can provide greater control over fuel consumption, some users may find that the fuel savings are not as substantial as they expected. The effectiveness of AFM and DFM systems varies from one vehicle to another, and some modern engines are already highly efficient without the need for deactivation.
Potential for Increased Fuel Costs
Deactivating AFM and DFM systems can lead to increased fuel consumption during regular driving conditions. If fuel efficiency is a top priority for your vehicle, the trade-off between improved performance and potential fuel costs should be carefully considered.
Legal and Emissions Concerns
Some regions have strict emissions regulations, and tampering with emission control systems, including AFM and DFM, can result in legal and compliance issues. Before installing the DISABLER, it’s crucial to research local emissions laws and ensure that the product doesn’t violate any regulations in your area.
Compatibility Limitations
While the DISABLER is compatible with a wide range of GM vehicles, it may not work with all models or engine variants. Buyers should verify compatibility with their specific vehicle before purchasing to avoid potential disappointment.
Final Words
The Southwest Speed New Range Technology AFM-DFM DISABLER is a product that offers both pros and cons, making it a suitable choice for some GM vehicle owners while less appealing to others.
Its ability to enhance engine performance, increase engine longevity, and provide control over fuel economy is undoubtedly appealing. However, potential warranty concerns, limited fuel savings, and compatibility issues should be carefully considered.
Ultimately, whether the DISABLER is right for you depends on your specific priorities and driving habits. If you value improved performance and are willing to accept potential trade-offs in fuel efficiency, this device may be an excellent addition to your GM vehicle.
However, it’s crucial to conduct thorough research, consult with your dealership, and ensure compliance with local emissions laws before making a decision.
