What is the Duramax Predator? The Predator for 2001-2004 Duramax is a state-of-the art high performance tuning flash programmer, which advances the injection timing, optimizes the injection pulse width. Unlike other "tuners", DiabloSportís programming is performed in very small increments throughout the entire RPM range, for a smoother, wider and a more predictable power delivery.

Why to get DiabloSport Predator?
  • Now Internet Updateable with version 9R01 and above. The Serial PC Interface kit is required to take advantage of the internet updating feature.

  • The flash tuner with most extensive diagnostic capabilities. Predator will read and erase fault codes, monitor live data, re-sets fault codes automatically when factory tune is restored to the vehicle.
  • The flash tuner with a true graphical display that's 300% larger then the competition's puny text only display
  • The flash tuner running on a custom high performance, multi-threading KROS operating system


Dyno Tested Performance Tunes

The Predator was created with one thing in mind, POWER!

A Predator equipped vehicle will notice significant improvements in drivability. The additional power created by the Predator tune will yield quicker acceleration, better mileage and improved towing characteristics, whether it is in town or out on the highway towing an 8,000 lbs trailer.

The power increase in the lower RPMs will yield a better throttle response; help maintain speeds on inclines and towing. The wider power band that the Predator creates will be particularly noticeable in city driving, where speeds constantly change. The mid-to-upper power increase is extremely useful on the highway when passing slower vehicles and to quickly maneuver out of emergency situations.

Predator contains five tunes to choose from:

  • Stock Tune: with adjustable speed limiters. Speed limiter to approximately 120 MPH varies based on vehicle, set-up weight, tire size, 2wd vs. 4wd, etc.
  • 40 RWHP and 100-ft/lb TQ - Tow Tune, made specifically for towing. DiabloSport recommended weight limitations based on manufacturer suggested limits for the vehicle.
  • 65 RWHP and 150-ft/lb TQ - Economy Performance Tune, designed for Economy and Performance, fuel economy depends solely on driving style, and will vary from vehicle to vehicle. DiabloSport recommended weight limitations of 8,000 Lbs.
  • 85 RWHP and 195-ft/lb TQ - Performance Tune, designed specifically for performance street driving. DiabloSport recommends this tune not be used for towing.
  • 120 RWHP and 240-ft/lb TQ - XPerformance 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.

Adjustable Parameters

The Predator features end user adjustable parameters so the end user can customize his/her tune depending on other modifications done to the vehicle.

The Predator allows the end user to adjust the following parameters:

  • Speed Limiters
  • Re-Calibrate Speedometer for Gear Changes
  • Re-Calibrate Speedometer for Tire Size Changes
