A small amount of soot is normal if you flat mat it before the turbo fully spools and the larger tires are going to make it a little bit lazier down low. Honestly if you were expecting to get 20 mpg with this your barking up the wrong tree, sell it and buy an old ass dodge. ^^^ This. The tires alone will cause some issues with economy, especially if you’re trying to calculate MPG off of a calculated number. On top of that, with the lift, you will experience increased air resistance by exposing some of the less aerodynamic parts on the truck. From what I have read and experienced, the powerstrokes have the lowest fuel economy for DD. That being said, people like them because they do work. MPG is definitely best in an older cummins 2wd. --- _[View the full topic](https://forums.speedlife.net/t/power-stroke-help/267922)._
