Performance chips, also known as engine control units (ECUs) or tuning chips, are electronic devices that modify your car’s engine control unit to optimize performance. The ECU is responsible for managing various aspects of your vehicle, including fuel-air mixture, ignition timing, and turbocharger boost levels.

As the name suggests, a performance chip is a chip that installs in your car to give you more power and torque, as well as a smoother ride and improved MPGs. The most common purpose of a performance tuner is to increase horsepower, but chips can also provide better fuel economy, sharper throttle response, and higher torque for towing heavy loads.

Performance chips have been a hot topic for car enthusiasts for years now. These small electronic devices are designed to alter the ECU, or engine control unit, of your vehicle. They have the ability to change a variety of parameters in your car, such as fuel-air ratio, ignition timing, and more, in order to increase performance.
