That's great news!~

My 6.4 mileage sucked when it was stock......the DPF failed in March, and I did a DOC/DPF delete w/ H&S tuner as it was cheaper than replacing the DPF. The mileage is significantly better, but with 1200+ ft/lb of torque on tap, I'm always into the throttle and mileage suffers.

The 6.2 should be fun
