By their very nature, diesels get good mileage, but what if you could optimize that fuel mileage? You can with the Economy Xcelerator. It???s been designed for the fuel economy-minded diesel owner looking for mild horsepower and torque increase along with a significant boost in mileage. It offers 3 horsepower levels (40, 90 and 120hp) and can up the torque settings up a full 200lbs. over stock. That means added towing capabilities while still giving you the ability to pass gas stations with a smile on your face. As with our other diesel Xcelerator models, the Economy Xcelerator can also make adjustments for larger wheel/tire combos, raise top-speed limits, transmission shift points and feature all the benefits that the other units in out Xcelerator line provide.
