| Leaving the DPF on, you will see a 1-2 mpg gain max, removing it, the mileage increase incredibly. It would be more like a 3-4 mpg gain. These are hand calcualted numbers on my truck.
I would go with a PPE standard if keeping the DPF, and if you want to remove it, you could use a Quadzilla S2 or PPE hot+2 race. Last I checked the Evo Race doesn't work with cab and chassis trucks.
