Frequently Asked Questions

What is an AFM/DFM Disabler and why would I need one?

AFM (Active Fuel Management) and DFM (Dynamic Fuel Management) are GM technologies that shut down cylinders (e.g., turning a V8 into a V4) to save fuel. A disabler plugs into the OBD port and prevents this deactivation, resulting in consistent V8 power, smoother acceleration, and often better exhaust sound, while also potentially reducing wear on related engine components.

Does a throttle controller actually increase horsepower?

No. A throttle response controller (like Pedal Commander) does not increase horsepower or torque. It works by adjusting the electronic signal from your accelerator pedal to the engine control unit (ECU), making the throttle body open faster in response to pedal input, which gives the *feeling* of instant power and eliminates frustrating lag.

What are the signs of a failing fuel pump or regulator?

Common signs include difficulty starting the engine, misfires, poor acceleration (especially under load), sputtering at high speeds, and a noticeable drop in fuel economy. For high-pressure direct injection systems, a failing HPFP can trigger specific engine codes.

Are these performance fuel system parts difficult to install?

Installation difficulty varies. AFM disablers and throttle controllers are typically plug-and-play and take minutes. Replacing internal fuel pump assemblies or high-pressure fuel pumps (HPFPs) is significantly more complex, often requiring specialized tools and professional mechanical knowledge due to safety concerns related to high fuel pressure.

Final Thoughts

Upgrading your vehicle's fuel system is a fundamental step toward achieving better performance, reliability, and responsiveness. Whether you seek immediate throttle response from a Pedal Commander or consistent power delivery from an AFM disabler, the products listed above represent some of the best ways to enhance your driving experience. Review your vehicle's specific needs and choose the high-quality components that will help you unlock its full potential. Shop now and feel the difference!
