  • Improved Torque: Alongside horsepower, torque is also enhanced. This results in better acceleration and overall responsiveness.
  • Better Fuel Efficiency: While performance is often the focus, many tunes also improve fuel efficiency, especially when driven conservatively.
  • Customizability: Aftermarket tunes can be tailored to suit individual driving styles and preferences, allowing drivers to choose between performance and comfort settings.
  • Enhanced Throttle Response: ECU tuning can lead to sharper throttle response, making the car feel more agile and lively.
