The most common way to tune a Ford Ranger is by remapping your Ford’s ECU (electronic control unit) to match your needs.
Your Ford’s current modifications are focused on safety and are likely not taking full advantage of your car’s power. Tuning a vehicle can increase its performance, upgrade its fuel efficiency, up its horsepower, and more.
However, tuning messes with the Ford Ranger’s main computer. If done incorrectly, a tune can seriously damage your car. On top of that, it is illegal in some states and can void your warranty.
