3500 DRW MPG's before/after delete/tune

[Trupiano]

Just wondering what others are seeing with their dully's with and without deletes and tunes. I'm not ever my concerned with MPG's but my previous 2500 went from 14 pre-delete to 19-21 after deletes. Definately easier on the wallet at the pumps.


I have a 2011 3500 DRW w/ 6 inch lift and 35 Nitto MT's.

Current pre-delete:

I'm seeing about 13.9 MPG on Evic, with 12.8 hand calculated. 65% highway, 30% city, 5% warm-up idle.

Ill be swapping the springs and blocks from a 6 down to a 3 inch this weekend, but I doubt that will make much of a difference.

I'm planning on using draconian diesel for custom tuning, and their MM3 setup when the time comes. Ill remove the EGR, but I'll just get delete pipes for the exhaust so I can return to stock if ever needed.

Let me know what you're seeing.

Really? 22-26 MPG for a dually?

I find that sort of hard to believe when I have 34's and a 3 inch lift and I'm at 12-13.

Lol, yeah that's not happening with a 6.7 in any body style.
I've never had a DRW, just SRW so my numbers may be slightly higher.

2007 6.7, reverse level, 33" tires (305/55/20),fully deleted, 3.73 gearing, T4 366 turbo, draconian tuned TCM and draconian EFI-live tuning.
12-13mpg in town
14-16mpg highway.

Current truck:
07 6.7, 2" level, 33" tires (305/55/20), EGR unplugged, 3.73 gearing, delete exhaust, unsure on tuning (no codes).
13-14mpg in town
18-19mpg highway

Both vehicle highway calculations were 95% highway (calculated over 150 total trips between 80-220 miles each)
In town calculations for the first truck were over 4 years @ 85% in town and the second truck just over a month on the same commute path (but they are so close, it's almost a moot point).
