Rye, just wondering what gain could be expected on a stock truck. I need mileage!

RyeThomas

Hard to say, they haven't cracked the Programming for your truck so theirs no data. Anything would be a mere guess on my part. I can say over the last 10 years and 3 of these trucks this is the first real gain in mileage I have ever experienced and I have tried a lot of mods, products, and combos. I am being modest at a solid 2 mpg gain no matter empty or towing thus far.

Just wanted to post up that I have been towing 10-12k + with my one and only EFI live tune. No changing, no switching anything. Simply hook up trailer, load trailer, and drive, PRICELESS.

And that's the light load with dry wood. I haven't gotten pics of the trailer loaded with the big green oak stuff.
