Add Power and Torque (15-20 HP/ Ft./Lb Tq) to your Chevrolet Avalanche 2003-2003 8.1L with a Diablosport Predator Power Tuning System.
The Predator is a state-of-the art, high performance tuning flash programmer in a sleek handheld design. Once connected to the vehicles ODBC connection, 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.
