Understanding the AFM System

Before we dive into the specifics of the AFM delete kit and performance cam, let’s first understand what the AFM system is and why it may need to be modified. The Active Fuel Management system, also known as cylinder deactivation, is a technology implemented by General Motors to improve fuel efficiency. It allows the engine to deactivate specific cylinders during light-load conditions, such as highway cruising, to conserve fuel. While this system may be beneficial for fuel economy, it can lead to various issues, including oil consumption, lifter failure, and reduced engine performance.

The Benefits of the AFM Delete Kit

The AFM delete kit is designed to eliminate the AFM system, providing a solution to the problems associated with it. By removing the AFM components and replacing them with non-AFM counterparts, the engine operates in a traditional V8 mode at all times. This not only eliminates the potential issues caused by the AFM system but also allows for improved engine performance. The AFM delete kit ensures that all cylinders are constantly firing, resulting in a more balanced power delivery and enhanced throttle response.

Enhancing Performance with a Performance Camshaft

While the AFM delete kit alone can significantly improve engine performance, pairing it with a performance camshaft takes it to the next level. A performance camshaft is designed to optimize valve lift and duration, allowing for increased airflow into the combustion chamber. This leads to improved horsepower and torque throughout the RPM range. By replacing the stock camshaft with a performance cam, you can unleash the true potential of your 5.3-liter V8 engine.

Installation Process

Installing a 5.3 AFM delete kit with performance cam requires some mechanical knowledge and expertise. It is recommended to consult a professional or experienced mechanic for the installation process. However, for those who are confident in their abilities, here is a general overview of the installation steps:

  1. Begin by disconnecting the battery to ensure safety during the installation process.
  2. Remove the necessary components to access the AFM system, including the intake manifold, valve covers, and timing cover.
  3. Remove the AFM lifters and replace them with non-AFM lifters from the delete kit.
  4. Install the performance camshaft, ensuring proper alignment and torque specifications.
  5. Reassemble the engine components, following the reverse order of removal.
  6. Double-check all connections and ensure everything is properly tightened.
  7. Reconnect the battery and start the engine to verify proper operation.

It is important to note that the installation process may vary depending on the specific AFM delete kit and performance camshaft being used. Always refer to the manufacturer’s instructions and guidelines for the most accurate and up-to-date information.

The Impact on Performance

Once the 5.3 AFM delete kit with performance cam is installed, you can expect a significant improvement in your vehicle’s performance. The elimination of the AFM system allows for consistent power delivery across all cylinders, resulting in enhanced throttle response and increased horsepower. The performance camshaft further optimizes airflow, providing a noticeable boost in torque throughout the RPM range. With this modification, your 5.3-liter V8 engine will truly come alive, delivering a thrilling driving experience.

Frequently Asked Questions (FAQ)

1. Is the AFM delete kit with a performance cam legal?
Yes, the AFM delete kit with a performance camshaft is legal for off-road and racing use only. It is important to comply with local laws and regulations regarding emissions and vehicle modifications.

2. Will installing the AFM delete kit void my vehicle’s warranty?
Modifying your vehicle with an AFM delete kit and performance camshaft may void certain aspects of your vehicle’s warranty. It is recommended to check with your vehicle manufacturer or dealership for specific warranty information.

3. Can I install the AFM delete kit and performance camshaft myself?
While it is possible to install the AFM delete kit and performance camshaft yourself, it is recommended to seek professional assistance unless you have experience and knowledge in engine modifications.

4. What other modifications can I pair with the AFM delete kit and performance camshaft for further performance gains?
When it comes to further performance gains, there are several modifications you can consider pairing with the AFM delete kit and performance camshaft. Some popular options include:

  • Cold Air Intake: Upgrading to a high-performance cold air intake system can improve airflow to the engine, resulting in increased horsepower and torque.
  • Exhaust System: Installing a high-flow exhaust system can help reduce backpressure and improve exhaust flow, further enhancing engine performance.
  • Tuning: Getting a custom tune for your vehicle’s engine management system can optimize performance parameters, maximizing the benefits of the AFM delete kit and performance camshaft.
  • Upgraded Fuel Injectors: If you’re looking to push your engine to its limits, upgrading to larger fuel injectors can provide the necessary fuel flow for increased power output.
  • Performance Headers: Upgrading to performance headers can improve exhaust scavenging and increase horsepower and torque.

It is important to note that these modifications may require additional tuning and adjustments to ensure proper compatibility and performance. Consulting with a professional tuner or performance shop is recommended to achieve the best results.

5. What are the potential drawbacks of installing the AFM delete kit with a performance camshaft?
While the AFM delete kit with a performance camshaft offers significant performance improvements, there are a few potential drawbacks to consider. These include:

  • Increased Fuel Consumption: Removing the AFM system and installing a performance camshaft can lead to increased fuel consumption, especially during aggressive driving.
  • Reduced Fuel Efficiency: Without the AFM system’s cylinder deactivation feature, fuel efficiency may be slightly reduced during light-load conditions.
  • Increased Engine Noise: The performance camshaft may result in increased engine noise, particularly at higher RPMs. This is a trade-off for the enhanced performance it provides.

It is important to weigh these potential drawbacks against the performance gains you desire and consider your specific driving needs and preferences.

Here are my recommendations for a top-quality 5.3 AFM delete kit with performance cam upgrade:

Banks Power Monster Performance Pack – One of the most popular choices. Contains a proven cam, pushrods, and AFM delete harness. Plug-and-play install and dyno-proven to add 50+ whp. Around $900 shipped.

SCT X4 Tuner w/ AFM Delete – For those wanting to retain their factory cam but still remove AFM. Provides a base tune and easy monitoring/tuning capabilities. SCT is a trusted brand. $500 kit.
