6.7 Gas Mileage Tune

bricewise · Mar 22, 2013

Got the newest SPE tune and loving it for putting around town. Going on a road trip and would like a more gas efficient tune. Anybody have any suggestions for a tune that they would suggest? If not thought about asking SPE.

Yes!!! Mileage tune would certainly get me to buy. Especially if it's shift on the fly, one tune for mileage and one for power.
I would buy if a mileage tune was avail.

Kind of what I was thinking TrickTruck. If the SPE tune had a mileage tune added in with their badass power tune..I'd buy that for sure

In my past experience fellas; the higher HP tunes tend to yield the best mpg, if, you can keep your foot out of it... :tree:

SPE, if you all would make a package for a good tow tune, one that gets great milage, then your hot one for the power it would be great. I would really like to see the tow and milage tunes have a max boost of about 28-29 psi to help save these crappy turbos a little bit on long pulls up hills especially. My truck will run 31-32psi all the way up which I don't care for if I am towing.

I just pulled a big bumper pull camper on the new xhot tune on mild amd the egts never even hit 900. 12 mpg as well. Tjats going up and down the hills of Ky.

Mystic, how fast were you going to get 12mpg.

I pulled a little trailer w/ a bike on it 400+mi to Daytona and back and got 12mpg...but I was doing 80 the whole way.
H&S 'performance' tune.

Pulling my gooseneck with a decent load about 10k running 80 I get 10.5-11 mpgs with my h&s. empty I stay in the mid 17's regular with low 18's sometimes.
