Before tuning your car, it’s important to have a clear idea of what you want to achieve. You can improve your vehicle’s speed, fuel efficiency, and drivability by adjusting ignition timing, air-fuel ratios, spark plug gaps, and engine chips. Make sure to communicate your goals to your tuner, whether it be for speed, a fuel system upgrade, or a smooth ride. Before tuning, have a tune-up to make sure your vehicle is in good condition. Choose your tuner carefully, as your car’s engine is controlled by an electronic control unit that a professional tuner can remap for improved performance. Know that tuning can be a time-intensive process, involving modifications to engine parts, brakes, suspension, and tires. You’ll also have to report the changes to your insurance company, which may result in higher premiums. Consider the pros and cons of tuning, including increased fuel consumption, stress on your engine, and voiding your warranty.
