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.
100 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.
