As car enthusiasts, we always look for ways to enhance our driving experience, whether it’s through improved handling, increased horsepower, or better fuel efficiency. One such solution that has gained popularity in recent years is the installation of performance chips. But what exactly are performance chips, and how do they work? In this beginner’s guide, we’ll answer those questions and more.

Performance chips are a popular modification for car enthusiasts looking to improve the performance of their vehicle. A performance chip is a small electronic device that modifies the engine’s computer to optimize its performance. Performance chips are designed to increase horsepower, torque, and fuel efficiency, while also improving the engine’s overall performance.

What are performance chips?

Performance chips are aftermarket devices that are designed to modify the engine’s computer, which is responsible for controlling various engine functions, such as fuel injection, ignition timing, and air/fuel ratio. By modifying the engine’s computer, a performance chip can optimize the engine’s performance and enhance its overall efficiency.

How do performance chips work?

Performance chips work by modifying the engine’s computer to improve its performance. The engine’s computer, also known as the engine control unit (ECU), is responsible for controlling various engine functions, such as fuel injection, ignition timing, and air/fuel ratio. Performance chips are designed to modify the signals sent from the ECU to the engine, thereby optimizing its performance.

Performance chips work by remapping the engine’s computer to adjust the air/fuel ratio, ignition timing, and other variables that affect engine performance. The performance chip alters the factory settings and optimizes the engine’s performance to enhance its overall output.

Benefits of performance chips

Performance chips offer numerous benefits for car enthusiasts. Some of the key benefits include:

  • Increased horsepower and torque
  • Improved acceleration and throttle response
  • Enhanced fuel efficiency
  • Improved engine longevityRocket Chip performance chip, black in color-RocketChip
  • Better towing and hauling capabilities
  • Improved handling and overall performance

Types of performance chips

There are several types of performance chips available on the market. The most common types include:

Plug-and-play chips

Plug-and-play chips are the easiest to install and require no modifications to the vehicle’s existing wiring. These chips can be plugged directly into the OBD-II port, which is located under the dashboard, and will automatically modify the engine’s computer to optimize its performance.

Piggyback chips

Piggyback chips are installed in parallel with the engine’s existing computer and work by intercepting and modifying signals sent to the engine. These chips can be more complex to install than plug-and-play chips, but they offer greater flexibility and control over the engine’s performance.

Remapping chips

Remapping chips involve completely overwriting the factory settings in the engine’s computer with new settings that optimize its performance. This type of chip requires professional installation and can be the most expensive option, but it offers the greatest level of performance optimization.

Precautions to take when using performance chips

There are several precautions that should be taken when using performance chips to ensure their safe and effective use. Some of these include:

  • Ensuring that the performance chip is compatible with the vehicle’s make and model
  • Following the manufacturer’s installation instructions carefully
  • Monitoring the engine’s performance after installation to ensure that it is running optimally
  • Regularly maintaining the vehicle to ensure its overall performance

Performance chips vs. engine tuning

Performance chips and engine tuning are both methods of optimizing the engine’s performance. However, performance chips are a more cost-effective and less invasive option, while engine tuning involves physically modifying the engine’s components to improve its performance. Both options offer benefits for car enthusiasts, but performance chips are a more accessible option for beginners.


Performance chips are a popular and effective way to optimize a vehicle’s performance, and they offer numerous benefits for car enthusiasts. Whether you’re looking to increase horsepower, torque, fuel efficiency, or overall performance, a performance chip can help you achieve your goals. By understanding how performance chips work and taking the necessary precautions, you can safely and effectively install a performance chip and enhance your driving experience.
