6.4l tune for fuel economy only

[rberg31]

Ok, so I have been reading posts and threads concerning tunes for the 6.4L and i'm not planning on taking my truck to the drag strip anytime soon, my question is does anyone know or have a recommendation on a tuner that will clear codes in order to run a dpf delete and straight pipe, but at the same time keep the factory tune for reliability and or a tune geared strictly for economy? Thanks for any advice!

There's a few that offer a simple Regen Off option where all it does is turn off the Regen function.

Spartan and H&S both do, I think SCT does as well.

Thanks for the heads up. Hopefully someone may chime in that has done this and can shed some light on the pros-cons of this type of mod...like I said, I dont plan to run my truck at a drag strip, but would like to increase fuel economy and, if possible, keep the engine as durable as possible as we all know problems can be costly if the vehicle is out of warrenty.

When I did the Spartan on my 2008 I tried all the DPF delete tunes and found the 210 hp offered the best MPG, Makes sense that more HP will provide the best economy, how You drive it is up to you, I did the delete and tune on my 2010, and again the 210 HP worked
the best for mpgs, as far as smoke I found that 40 hp produces least smoke at about 2 Mpg less

You say it makes sense that more HP will provide the best economy...why? Seems to me, if I understand the whole tune thing correctly, is that the tunes that create more HP do so by dumping more fuel. Wouldnt that be worse for fuel economy??

I'm sure that someone much smarter in this sense than myself will chime in soon, but yes, as long as your right foot isn't heavy you will get better mileage with the higher HP tunes mine went up about 4-7mpg running the 250 tune. Less effort to make by the engine to get the big beast movin.

i run the 310 tune daily and and get a honest 22 mpg with my crewcab 4x4 and that is with a calculator!! with the higher horsepower tunes the truck is not lugging at all

22 MPG, wow! I just filled up this afternoon, hand calculated 15.2 mpg. that is mostly city driving as there is a 5 mile strecth of higway that I can run 60-70 mph twice daily. My truck is stock and will remain stock untill my truck reaches 60K. that should give me about a another year stock...plenty of time to read and see how you guys make out with your tuned 6.4's with dpf delete. I am wanting to mod my 6.4L, just dont want to do so until warrenty is up

Warranty is a bunch of tomfoolery. About as gay as a tandem bikeride to a pic-nic. I'm on my 3rd Rad at 75k miles and they haven't done anything! Oh! A 'Venturi' T update that didn't do squat!

My truck has 6700 hours BTW, and I finally did my Spartan full exhaust delete a month ago. Have been running the 210 tune, and my wife is getting 100kms more per tank in town so far. Change your Oil and fuel filters properly, that's the most important thing.

Oh! even with the 210 tune, I broke 35" M/T's loose getting going, and squeeled the 2nd gear shift. Do it sooner then later

you are going to find a ton of posts on this and get 100 different opinions. My best fuel milage is with the Spartan 350 if I can keep it at 60-65 mph all day. If I speed up or slow down the milage changes a lot. same with the 310 which is my second best milage tune, I dont get sh t for milage with the 210. And I have never gotten any where near 22 mpg with any tune at any speed and trust me I've tried everything. My best is 16.9 using the 350. using the 310 average is about 15mpg. I hand calculate every fill up. when running the 350 and got 16.9mpg my gauge said I was getting 24mpg.
