which programer for 6.4L?

[Bigaustin57]

I have a 08' F250. Im getting around 12.5 mpg. Im going to get a programer and was wanting to get some opinions. Im not really looking for power, i'm mostly looking to improve my mpg. I was looking into the spartan, and wondering if it had a gas saver tune? thanks for all help

You will usually get the best economy out of a high performance tune. Spartan has shown hit and miss reliability with their customer service, but is still some of the best tuning around. H&S is another popular option. It all comes down to which unit (that gives you readouts and loads the tunes) you like more.

Also, it's FUEL MILEAGE, not GAS.

I recommend Spartan. If you have any questions feel free to PM me or email me.

At best I get 14-15 mpg on the highway and when towing my 5th wheel 9 - 10. What is the investment in tuning for fuel economy only and what is the return?
What stresses does tuning the engine introduce? When I tuned my 05' 6.0 the concern was head gaskets...thanks

If I were you I'd do a lot of reading and asking questions concerning the mpg improvements. I tuned my truck (pretty much the basics) and I'm not seeing these miraculous improvements that you read about here. Big power but that wasn't my main objective. Sorely disappointed with the MPG on my "tuned" truck.

H&S Mini Maxx

AFE stage 2 intake,h&s mini maxx,dpf/doc delete. Tried about everything I can think of and have just about quit checking the damn mileage. It's not going to happen for me I guess. Had I known that I'd have left it alone.

The power is nice but a "worry free" warranty on a brand new truck has something to be said for it as well ya know? $1500 invested sure isn't going to be recovered in fuel savings here!

I would read this.

The Ultimate DPF delete SHOWDOWN!

Thanks for the honest feedback. I am not surprised. I chipped my 05' 6.0; installed 4" exhaust and a new air intake all for promised fuel economy. I maybe saw a 1 mile per gallon increase. Not worth the investment and voidance of the truck warranty.

I'd beg to differ, especially with the 6.4's. Ridding the truck of regen and the high egts during regen will increase longevity. Also, firmer shifting can be fun, but also can reduce wear on clutch packs.

And can you honestly say, having well over 400 horse under your right foot is a bad thing? Also, for mixed driving, you won't see a huge mileage difference, but still some. And you also have to keep in mind, some trucks just suck for mileage more than others, even if identical.
