Not real happy with my H&S and deletes.
 

So ive put on 2,000 miles on after installing H&S mini maxx with all deletes on my 2012 6.7 with auto, 3:73.
My MPG is still 16 MPG, same as stock. Not real happy, I've tried every setting on the mini maxx and did the update before I installed it.

I can get 18 mpg if I do 55 mph. I can't drive under 70. I do mostly highway driving.

What mini maxx settings do you find the best MPG for highway?:argh:

I find the hot tune to be the best for the highway. It's all about power to weight ratio!

Thanks! I will try it.

EFI live brother it's the way to go

Except for the fact you can't get it for a 12. Only reason I don't have one, and now with the epa shutdown on the deletes it's not going to happen

MCC is basically the same thing.

Yea very true times are changing

i got mine on 4 mild and driving 75 i get 16.6 hand calculated

I always tell guys not to mod for mileage, because they're typically disappointed. Usually with DPF off stuff you can gain some. How are you driving? Are you using that new found power out more now? Like others have said, usually the hottest tunes yield the best mileage.

Where are you located?
