If you have owned a Mustang in the last 15 years, chances are that you have seen a Predator in action. We're excited because Predator is now back and better than ever ! On the legendary Mustang, we can add up to 40 horsepower and 50 Ft/Lbs of torque when running 93 octane along with a huge mid-range torque gain that will open the car up like never before. Couple the power gains with the Diablo tune's crisp, performance-style shifts and your upgraded Mustang will drive better than the day you bought it! With the Predator you can also tweak your tune to do things like remove your top speed limiter (perfect for your track top speed), adjust your cooling fan on/off temps, or even set up your car's speed/trans for an aftermarket gear swap. The legendary Predator Tuner is the single best upgrade you can do for your Mustang- running the Predator will get you more power, and options, than any other single bolt-on you can install on your car, and all at an incredibly affordable price!
