What is Duramax Predator?
The Duramax Predator is a state-of-the art high performance tuning flash programmer, which advances the injection timing, optimizes the injection pulse width. 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.

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

The Predator comes with 5 different tuning levels:

40HP tow tune, designed to add power and torque specifically for towing
65HP economy performance tune, designed to add power and torque with fuel economy in mind
85HP performance tune, designed to add power and torque for the street driven performance enthusiast
120HP Extreme performance tune, extreme power and torque
Stock Tune with speed limiter, axle ratio and tire size adjustment
The Predators additional power makes itself noticeable immediately with an increase in power that starts in the low RPMs and builds into a frenzy at the high RPMs.

Performance Gains
A Predator equipped vehicle will notice significant improvements in drivability, whether it is in town or out on the highway towing an 8000lbs 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.

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 Duramax Predator allows end user to adjust the following parameters:

Axle Ratio
Tire Size
Speed Limit

Diagnostic Features
