Tuning your 7.3 Powerstroke will improve performance, gas mileage, horsepower, and add hundreds of pounds of torque. While there are a lot of different aspects that can be customized on your truck, the engine is the most important one.
The difference between driving something that has been tuned and a standard vehicle is night and day. Once you experience it, you'll never want to go back to using a regular factory model car. And if you own a vehicle with a 7.3 liter Ford Powerstroke engine, you're sitting on the holy grail of customization. With the right equipment you can make modifications to almost everything, including gas mileage and horsepower.
