- Sound: Choose a system that matches your desired exhaust note.
3. Engine Tuning
Engine tuning is another effective way to enhance performance. Tuning optimizes the engine’s air-fuel mixture and ignition timing, leading to improved performance and efficiency.
Benefits of Tuning
Here are some benefits of tuning your XJ Cherokee:
- Improved horsepower and torque.
- Better throttle response.
- Increased fuel efficiency.
How to Tune Your XJ Cherokee
Tuning can be done through various methods:
- Using a handheld tuner or programmer.
