Done some driving this weekend without the DPF. Before I was showing 16.4 on the overhead. Now, without the DPF I'm showing 18.8. I'm going to fill back up in the morning and hand calculate it. Can't wait to take off the EGR. :hyper:

This is exciting to hear! I am getting 16-18 mpg empty and I have 434 miles on mine... If the DPF delete really does that well I am yanking mine off ASAP!

My fuel economy is almost the same.
Dont get too frustrated, my 6.7 5500 gets an easy 30% better fuel economy than my 6.4 550. Both trucks are within 100 pounds of each other, have the same gear ratio and same winchbed setup.
