The DiabloSport Extreme PowerPuck for the 3.0L Dodge Sprinter Van/3.0L Jeep GC is one of the most powerful inline devices available today. Using the “Diablo Dial” you can adjust up to 100 different power levels “on the fly” which can yield up to an additional 50 horsepower and torque. With the Extreme PowerPuck’s additional torque output towing is no problem. If you are looking to save some money at the pump-go no further, the Extreme PowerPuck can increase your fuel economy by 2-4 miles per gallon (just watch that “lead foot syndrome”).
