My dad has a 6.7 and wants some kind of chip to help his mileage. It's not getting as good as mileage as his 03 and the truck has over 20K, so it should be past the break in period. My dad hauls cattle and hay several times a week and is tired of getting single digit mileage. As soon as it regens, mileage can drop as much as 3-4 mpg. My question is, is there any chips or programmers out yet that leaves no footprint on the ECM? I know the Smarty doesn't, but it won't be out for several months. I'm trying to convince him to just wait for the Smarty[guitar]. Is this the best thing to do? Thanks.

That is the only thing I would consider. A buddy beta tested a Edge Juice W/Att on a 6.7 and saw no change in mileage.:( So he sent the truck back to the dealer, and the the box back to Edge. He traded for a 5.9, and hasnt looked back since.
