To tune your Mazda, you’ll remap your car’s ECU (electronic control unit) to enhance certain performance capabilities. Your ECU is currently focused on safety, so it may not be utilizing your car’s full power. Tuning your car upgrades fuel efficiency, horsepower, acceleration, and more.
However, there are notable risks and downsides. First, tuning is illegal in some states. Second, tuning your vehicle can void your warranty. Finally, tuning can damage your car if done incorrectly.
