I just took off my superchips and installed a Quadzilla Mileage Max. I was not impressed with the 3.42 gears only getting 23. so i figured i try something else to get me in the 25 range. I put the QMM in and WOW. My baby is sipping fuel. It's currently getting 25.8 with some city mixed in. I'm gonna try the next tank all highway and see how it does. I do miss the power from the Superchips going from 390 back to 235HP sucks but ill deal with it as long as diesel stays this high.
