The Dr. Performance System produces REAL WORLD power gains! They call this usable power - all the way across the power band at the speeds and in the gears where you need it. Their system also produces a very flat torque curve. This means, once maximum torque is reached, torque falls off very slowly as RPMs increase toward maximum horsepower. This gives your engine excellent pulling characteristics by keeping torque output high all the way up the power band until maximum horsepower and RPM is reached.
Whether you choose the Dr. Performance Triple Play Adjustable module or the Predator Nitro Flash programmer for the Chevy Duramax, you will have easily adjustable diesel performance. Or you can choose your power level with the Stage 1 through Stage 4 Predator modules for Dodge Cummins and Ford Powerstrokes. There's even a Dr. Performance Predator module for the Jeep Liberty diesel!
