5.7 and 6.1L Hemi Preditor Tuning kits





Diablo Sport Predator Tuner for Chrysler Hemis

2005-2007 Chrysler 300C 5.7/6.1 Hemi

2005-2007 Dodge Magnum 5.7/6.1 Hemi

2006-2007 Dodge Charger 5.7/6.1 Hemi

2006-2007 Jeep Grand Cherokee SRT-8 6.1 Hemi

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.

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 and improved shift patterns 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.
