What is the Diablosport Predator?
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.

Dyno Tested Performance Tunes
The Predator was created with one thing in mind, POWER!
Average power gains are per tune. 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.
A Predator equipped vehicle will notice significant improvements in drivability. The additional
power created by the Predator tune will yield quicker acceleration and better mileage, whether
it is in town or out on the highway.
The power increase in the lower RPMs will yield a better throttle response. 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.
