The DiabloSport Predator is the ultimate handheld tuner for 1998–2019 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the legendary Powerstroke diesel. Built for drivers who need more pulling power, better drivability, and serious performance, the Predator delivers dyno-proven results with simple plug-and-play installation. With the extreme performance tune, your Powerstroke can gain over 100 horsepower and 250 lb-ft of torque at the wheels—enough to transform your truck’s acceleration and towing confidence. Many owners also see up to 3 MPG improvements in fuel economy, making it a smart upgrade for both power and efficiency. Towing is where the Predator really shines. With dedicated towing calibrations, you’ll notice stronger mid-range torque, smoother throttle response, and improved drivability while still staying within your truck’s factory tow ratings. The tuner also allows you to recalibrate your speedometer for larger tires or gear ratio changes, adjust or remove the top speed limiter, and even check and clear diagnostic trouble codes. For Ford diesel truck owners who want serious horsepower, better towing performance, and everyday drivability improvements, the DiabloSport Predator is the proven upgrade that delivers power you can feel.
