NOTE: Very early calibrations are not supported, update by GM dealer to "Current Software" might be required for some.  GM Software update fixes numerous production bugs and is neccessary to ensure proper performance and tuning. 

To find out about the available PCM updates for your vehicle, please enter your VIN or CalID numbers at this website: GM Service Updates Database. This information will help you with getting the necessary GM dealer warranty update reflash if the Predator requests it.

This is not neccessary to do unless the Diablo Predator refuses to install because of an old GM PCM calibration.




What is the Duramax Predator?

The Predator for 2004.5-2005 Duramax LLY 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?
  • The flash tuner that offers five tunes
  • The flash tuner that offers extended speed limiters
  • Performance Tune changes made in less than 45 seconds
  • 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 140-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 170-ft/lb TQ - Performance Tune, designed specifically for performance street driving. DiabloSport recommends this tune not be used for towing.
  • 120 RWHP and 250-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


Vin Lock

The 2004.5-2005 Predator for the Duramax LLY will unlock itself from vehicle once original backup is restored so it can be used on another vehicle.

Diagnostics

The Predators diagnostic features allows end user scan and erase fault codes. Predator can read and erase fault codes, and contains all the GM diesel specific P codes. Predator diagnostics will work on all Chevy and GMC Duramax vehicles.
