The DiabloSport Extreme PowerPuck for the 3.0L Mercedes E320/ML320/GL320/R320 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. The Performance will be felt immediately. 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”).
