guys does anyone use any HP of FUEL Economy "chips" in their tow vehicles? Trying to find something to help a bit and just starting to research them - the 6.7mpg has to get better.

What are the stats of the truck? If it is an early 6 litre I would not use and type of "shift on the fly" tuners. These trucks are very grumpy with power adders and repair bills can add up. I can go into detail just need more truck info.

What truck/engine do you have? 6.0s respond very well to tuners, but may self-destruct when used a lot at the high-performance level.
6.4s will also respond well, but the DPF will have to go, and so will the warranty.
