Had to update programmer for this to take place. Downloaded an updater program, updated the programmer, reprogrammed the truck computer, all in about 30 minutes. Immediately noticed a more responsive, quicker to idle, more powerful engine. Drove a 1300 mile trip in first week. Mileage went from 10.2 to 12 mpg. Awesome.
