Squeezing every last bit of energy out of a gallon of diesel for improved mileage is just as much a science as making big horsepower gains. By tuning your vehicle's injection, ignition and transmission shift characteristics the Mileage XS delivers savings you can put in the bank instead of the tank.

The Mileage XS also lets you read and clear trouble cods, recalibrate the speedometer for tire size or gear ratio changes. Free updates are availabe using the internet update software. There is even an upgrade program that allows you to trade up from your fuel economy tuner to a more aggressive performance tuner such as VIVID, Flashpaq or Cortex.

MILEAGE XS PART NUMBERS: Ford Diesel - 1851, GM Diesel - 2851, Dodge RAM Diesel - 3851
