I recently made a trip to Dallas from NW Ark. and turned my stabilitrac off, both ways of travel. I didnt drive my normal speeds that I travel the interstate and instead ran around 80-90 but resullted in getting around 19.5 MPG.
I normally run about 72-75 and get around 17-18.5. Has anyone tried this or konw if turning the stabilitrac off can result in better fuel mileage? This really surprised me and just would like to know if I should turn it off for long trips in the future.

Also I almost always get an "engine power reduced" message when I first start driving but it never seems to effect actual performance and runs normal and code goes away shortly after flashing up. Any help on both would be great! Thanks!!

I turn traction control/stabilitrak off everytime I start the truck.
I dont like it controlling the engine speed management. Acceleration is better with it off.
On dry roads I dont need that stuff on. When roads are bad/wet I leave it on.
My MPG is the same with it on or off.

You mean turn it off? Press the button once to disable traction control (DIC will read "traction control off"), press/hold the button for a couple seconds will disable StabiliTrak. DIC will read "StabiliTrak off"

HD is right about turning off the TC/stabilatrac but I dont think your truck year model is equiped with stabilitrac Chanz. I think they started that in 09... I could be wrong but I think I have read that somewhere.

It might be that because of my larger tires my sweet spot is in that MPH range vs where I usually run on the interstate then. Thats the only other thing I can think of that I did different.

As stated above Stabilitrak is only available from 09 and up

I think its sounds more of a result of getting a stong tail wind, or just staying a constant speed for an extended period of time.

Yes sir. My speedo is corrected for tire size and I am running 305's. The tail wind aspect is very possible. That is the only time that I have run that speed for extended periods. I tend to run 77-80 cause I dont need a ticket. When running these speeds I see anywhere from 17.5-18.5.
