2014 6.7 f350 tuning/deleting

i am in kind of a hurry right now so i thought i would make a new thread, i'm sure this has been discussed 3000 times but here it goes. just got a 2014 f350 with a 6.7 in it (obviously thats why i'm in the 6.7 forum). it has 160,000 miles on it and i put on about 30k miles a year. i am looking at the mini-max system, deleting the egr, deleting the def, and putting on the cold air intake. what i am looking more for is better fuel mileage. will this help for fuel mileage but mostly longevity of the motor. i am not really looking for more power but if i did run it in hot mode am i looking for premature failure of the motor? my 2nd diesel but first time looking to delete. it is cold here and running number 1 and with the warmup time i am only getting about 13 miles per gallon and that just won't cut it.

Sold your 78, shame on you bet you regret that, LOL. I dont think H&S is supported anymore, recommend the EZ-LYNK and a tuner of your liking. I use GDP and am very happy. I have heard that the 11-14s will see 1-2 MPG gains while the 15 and up dont see much gain.

I wouldnt say you don't get much gain, at the very least the elimination of the regen will gain you a little. I can tool around town and use a somewhat easy going driving style and get 16-18, on the highway 17-21 depending on factors that affect MPG, (wind, temp,degree of aggitiation)

Thanks guys. Is it normal in the winter to get only 13 mpg on average? Like today is -10.

On very cold days you will notice a decline in MPG. I drive like 2 old people fornicating and I get about 16mpg in the winter and 18 in the summer months. By the way I'm old.

thanks f250 I have a lil bit of a heavier foot. And on your early question I loved my 78. It had a new 400 with 4 barrel Intake and carb and headers with true dual exhaust and 12 inch cherry bombs. 35 inch dick cepek mud countryís and a 4 inch suspension lift. It turned heads everywhere I went. I just didnít have time for it and traded it even up for my 2001 f350 crew cab diesel.

I am running a 60tow tune from tyrant now, only have had it loaded for 3 days, thus far like it better than the Rudy tunes I initially deleted with. I like the shifting better. If you really don’t care about power level switching, I’d go sct X4 with single tow tune, challenge is most will throw 3 or 4 tunes in a package for slightly more than a one off. FWIW, on best apple to apple comparison trip I have, saw ~20% improvement in fuel mileage. Delete, race pipe(resonator and muffler now) block off egr plates. Painted the tip black as well, looks stock almost sounds stock.

Have fun shopping!

I have the same truck, fully deleted and tuned with a EZ/Link tow tune, I love how smooth it runs and shifts now. On the interestate i lost about 1- 1/12 mpg because of the increase in rpm's,normal driving....main roads,back roads....i gained 1-2 mpg....But, I didnt do it for fuel milage, that was just a side benefit.

Totally agreed, seeing the regen screen for whatever reason would irritate me. Love the smell of diesel, I do like that in the tunes I have run this far, they are CONSIDERABLY cleaner for black smoke than my 7.3 was.

Skip the intake, you want the best air filtration so leave it stock.

The regen on my 2017 F450 takes 0.5 gallons of fuel about every 400 miles. At 15 MPG, I use 26.66 gallons of fuel. If I skipped the regen, I'd use 26.16 gallons. This is 15.28 MPG. That's right, the regens cost me a whopping 0.28 MPG.

To see this, I reset my trip computer right when a regen started and took this picture right after it ended (seen via Forscan). During the regen, I burned 1.51 gallons of fuel (15.4/10.2). I normally would burn 1.03 gallons during that distance.

Note, more fuel is needed for a regen if you don't drive far enough to finish it. This was a typical (and ideal) highway regen for my truck.

one last question, if i delete it and put a tuner on it, it won't roll coal will it? not a fan of that at all. i want to stay under the radar. i supposed when i was 20 that would have been awesome.

My sctx4 came with 3 or 4 tunes. The tow, which is least aggressive does not. Thatís what I run with. As you dial it up you get more smoke. The hot tune is pretty obscene.

I have only run tow tunes, you have to try really hard to see black smoke, maybe a haze at times, but nothing like coal. FWIW, I just loaded tyrant 60 tow last week and like the way it is working over what came from Rudy's diesel in the package. Trans strategy is much better thus far.

Weez440: My 2011 is deleted with MinMax race tuner. It is not a big coal roller, very little actually. I have 4" exhaust with muffler and stock tip. BEST thing I ever did for my truck! Like getting a whole new truck. Running on performance is a +250hp gain and gets your best mileage (or so they say). I commute across Houston in city/highway with traffic for 40 miles and I get 19-20 mph, best around 80 mph. My mileage was pretty similar before delete but I obviously do not have regens now and longevity was the motivation.
