Diablosport Predator Tuner (99-03 F150 & Harley Davidson - 4.6L or 5.4L)

Unleash Hidden Power. Unleash the true power of your truck's engine with a Diablosport Predator Tuner. This state-of-the-art, handheld flash programmer comes preloaded with dyno-proven tune files that optimize spark timing and air/fuel ratio curves for performance you can really feel.

Gain Up to 25RWHP. The Predator comes with a dyno-proven performance tune designed to deliver gains of up to 25 RWHP - and you'll never have to pick up a wrench to do it. On a stock 4.6L-powered F150, you can expect to gain up to 20RWHP and 25 ft/lbs of torque on the provided 91 octane tune. On a stock 5.4, you'll see up to 25RWHP and 30 ft/lbs of torque.

Adjust Critical Parameters. The Predator gives you the power to adjust critical engine parameters so you can customize the tune for any mods you've made to your F150 - including timing, injector size, gear and tire size, and much more. (See below for full list).

Live Datalogging. Need to know what's really going on inside your truck's powerplant? The Predator holds up to 30 minutes of high-rate sampled data and 90 minutes of reduced rate data. Plus the data can be view on the device or uploaded to your PC for viewing with the free Diablosport DAT Viewer for Windows Software.

Less Fuel & Less Shop Time. As though you needed another reason to get a Predator, this amazing device will even save you money by both improving fuel economy and providing built-in diagnostics. Save yourself a trip to the shop and find out what's wrong before you go. The Predator allows you to read and clear "check engine" lights so you know what the problem is before you make an appointment, saving you time and money.

Custom Tuneable. Ready to take the next step in performance? A Diablosport Predator can hold up to 3 custom tune files so you can maximize your specific mods and have a truck that runs better, stronger, and faster than you ever thought possible.
