What is the GM Predator?
The Predator for 1999-2002/3 GM V8 vehicles (part no. U7198) is a state-of-the art high performance tuning flash programmer, which advances the timing, optimizes the air/fuel ratio and remaps the transmission shift points (in automatic transmissions).
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.
Why to get DiabloSport Predator?
Dyno Tested Performance Tunes
The Predator was created with one thing in mind, POWER!
- The flash tuner that allows for end user adjustability
- The flash tuner which accepts custom tunes directly from DiabloSport or from ChipMaster Revolution dealers that you can install yourself
- The flash tuner with built-in advanced diagnostic capability that displays fault codes along with descriptions of the code right on the Predator screen
- The flash tuner with data monitoring capability
- 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
Average power gains for Performance tune are in the 20-30 RWHP range.
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 Tune: Designed to add power and torque using premium fuel.
- 87 Octane Tune: Designed to add power and torque using low to mid grade fuel.
- Factory Tune: Designed for users who wants to adjust parameters using the factory tune.
A Predator equipped vehicle will notice significant improvements in drivability.
The additional power and improved shift patterns created by the Predator tune will yield quicker acceleration, firmer shifts, 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.
The increase in MPG is a byproduct of maximized engine efficiency, the improved timing curve and air/fuel ratio creates a more complete combustion, i.e. the engine extracts more power from each molecule of gasoline.
Predator tunes re-map the:
DiabloSport Performance tunes require the use of Super Unleaded / Premium grade fuel only, like carried by Amoco/BP, Sunoco or Mobil.
- Fuel Curves
- Timing Curves
- Torque Management
- Extend Speed Limiters
- Extend Rev Limiters
- Disable CAGS (Skip Shift)
- Part and Full Throttle Shift Points
- Shift Timing
- Shift Presure
The Predator features end user adjustable parameters so the end user can customize his/her tune depending on other modifications done to the vehicle.
Because it allows for timing and fuel adjustments the end user can optimize the tune for his/hers specific vehicle utilizing a dyno with proper air fuel monitoring and utilizing the Predator's live data feature to monitor timing and other vital parameters.
The Predator allows the end user to adjust the following parameters:
Transmission functions do not apply to trucks with the Allison transmission.
- Timing Table 2000-4000rpm (+15/- 20%)
- Timing Table 4000-7000rpm (+15/- 20%)
- Fuel Table 2000-4000rpm (+/- 20%)

Diagnostics and Live Data Monitoring
The Predators diagnostic features allows end user scan and erase fault codes as well as monitor live data while driving.
Predator can read and erase fault codes, and contains all the manufacturer specific P codes.
Predator diagnostics will work on 2003 H2 Hummer vehicles.
The 1999-2002/3 Predator for GM revision 2.10 and up will unlock itself from vehicle once original
backup is restored so it can be used on another vehicle..
Custom Tuning can be done for almost any application without the need for the end user to send the Predator.
We have PC Interface kits and software available for download and the tunes can be sent via e-mails or you can go to a localy tuning facility.
