DPF/EGR Delete MPG?

[Balla6.7]

I have tried searching all over the internet but cant find any MPG gains going from stock to DPF/EGR DELETE w/ tune etc...

Any owners have 1st hand experience either with Spartan or H&S. Thanks

Most see an average of 2-4mpg gain.

Who cares? lol Isn't 550+hp worth it anyway?

[Balla6.7]

Yes its worth it alright.

Just never hear about anybody bragging about their MPG, Just their HP/TQ #'s. And a whole bunch of revving videos on YouTube.


Placing an order ASAP after Thanksgiving.

21.5 on the interstate at 74 mph
18 home to work
12.5 pulling my 13k lb fifth wheel
13 pulling my 11k lb excavator

Just turned 22k miles and have been deleted and tuned since 5k miles.
I am completely satisfied with my modifications.

Hows the sound with the 4'' & Muffler?

Thinking about going with a Straight 5''....

The 5" is too loud. I love the way straight sounds, but I've grown out of the "look at me" phase. 4" w/muffler suits me just fine. Plus, better torque and mpg with 4".

Do you have the DEF delete also?

[Scubamax]

Yeah. Mbrp 4" with muffler

I improved from 15.5mpg to 18.5mpg all hand calculated. Deleted def and turned off egr. stock tune to hot made no difference in my fuel mileage. Just run mild while pulling 16k and still get 12mpg.
