The Predator has been a legend in the LS performance community for years! In fact, many DiabloSport employees cut their teeth with tuners for the very first time running a U7198 Predator on their old F-Body LS1 cars! The great news is that the Predator is back and it is better than ever! You can expect the same awesome performance gains from this tuner as you did in the old days, but now with more creature comforts like USB updating, a color screen, and more. Running the Predator in your Camaro, Corvette, GTO or other GM muscle car, you can see gains of 25 horsepower and 30 ft/lbs of torque without having any other performance modifications installed. The Predator also lets you adjust cooling fan speeds, gear ratios, tire size, and other performance parameters to get your car running right at the track! Whether you've got a 5. 7L LS1, or a 6. 2L LS3, or something in between, the Predator is sure to be the easiest performance upgrade you install on your car, and definitely the one that gets you the best performance impact per dollar!
