The Predator is a state-of-the art, high performance tuning flash programmer in a sleek handheld design. Once connected to the vehicle, the Predators internal computer recognizes the vehicles PCM and automatically picks the proper tuning files designed specifically for that PCM. Inside the Predator's memory are the actual tuning files that optimize spark timing and air/fuel ratio curves. The transmission parameters are remapped to improve the shift characteristics such as shift firmness and shift points. Unlike other 'tuners', DiabloSport's programming is performed in very small increments throughout the entire RPM range, for a smoother, wider and a more predictable power delivery. DiabloSport engineers spend many hours on the dyno, street and track to ensure the tunes provided with the Predator are the best they can be.
U7186 Stock Vehicle Tunes:
  • 45 RWHP: Tow Tune, made specifically for towing. DiabloSport recommended weight limitations based on manufacturer suggested limits for the vehicle.
  • 65 RWHP: Economy Performance Tune, designed for Economy and Performance, fuel economy depends solely on driving style, and will vary from vehicle to vehicle.
  • 85 RWHP: Standard Performance Tune, designed for Economy and Performance, fuel economy depends solely on driving style, and will vary from vehicle to vehicle.
  • 120 RWHP: Extreme Tune, designed specifically for opening a can of whoop-ass (pardon the expression). DiabloSport recommends this tune not be used for towing.
    DiabloSport strongly recommends the use of larger diameter performance exhaust components and exhaust temperature gauges with the use of any performance diesel tuning.
