Fuel Mileage after DPF Delete
#16
I'm running an older H&S on the 300HP tune, don't drive it like I stole it.

Well, every truck is different, mine is 2WD which I think makes a sizable difference, and I don't drive 75, but I also don't drive 55. I do believe 65 is a sweet spot for the 6.4 and on the freeway mine is usually in the area unless I'm late for something. I do think 16-17 for a 4 WD at 75 is very reasonable for a 6.4.
As someone else mentioned, downhill, 65, in neutral and a tailwind just maybe you can get 16-17, oh yeah and drafting an 18 wheeler.
Just kidding, If you are consistently easy on the go button, steady 65 on the flat, level as a pool table and absolutely NO headwind you may can get 16-17.
Oh and slow granny starts help a lot. Just not my forte.

Fuel Mileage after DPF Delete
The last few tanks I have been very careful how I drive, trying to get maximum fuel economy. I just filled it up today and hand calculated it. 7.483km/L. That works out to 17.602 mi/gal.
That's 618.4km on 82.637 liters fuel.
I never pay close attention to what the LOM says but I think it's showing 13L/100 km. I don't know why it can't display km/L but at any rate, actual is 13.363L/100 km so it's not deplorably far out.

All these letters are out of my league. Delete DPF is what I want to do. My truck is regening every 70 miles. Too soon, right? What about passing smog test and do I need to do a manual clean on the DPF yearly just to keep it clear?
SPECS:
2008 F250 6.4L
6" lift on 20/37's

I installed a DPF-4 plus programmer with cat/ dpf delete and saw no increase in mpgs. Before the install the digital mpg readout said 18.2, actual was 15.4. After the install the digital is up to 23.2 and actual is 15.4. With a digital increase of 5 mpg, how can there be absolutley no corelation between the digital and the actual mpg?

I just recently went with Spartan and DOC/DPF delete pipe, nothing else. Before the tune/delete I was lucky to see 13 mpg, hand calculated. 12 mpg was more realistic and the LOM was within 1/2 mpg or hand calculations. Just hand calculated a tank with the 210 tune (finally keeping my foot out of it and enjoying all the power), my LOM said 17.8 but my hand calculation was 17.1. I know 1 tank calculation isnt enough data to prove anything, but clearly there is an increase and I will continue to get more calculations so I have an overall average.
