Became available for the 6.0 on September 9th for the Superchips 1815 Tuner, it's called Mileage XS Tuning. Supposedly up to 25% increase in fuel mileage. Free download update to existing 1815 tuners from Flashpaq.

 

Isn't the 1815 for gas burners?

 

Yes of course, the 1815 is the gasser tuner, the 1805 is the diesel tuner. Anyway, there is a new diesel fuel economy tune as of September 9, 2008 for the 6.0 diesel when you update 1805 flashpaq online. (Updates are free for registered owners.) I'm fixin to update my tuner and give it a try.

 

I have the 1805 as well. After reading your post, I went on the flashpaq site and read about the new tune. I'm curious if it is replacing one of the other tunes or if it is in addition to the other three.

You probably won't get much interest in this thread on here. There a lot more people with SCT's. I'm actually planning to go that route myself if I happen upon a good deal on one.

 

I down loaded it last night and WOW. I dont know about the fuel economy yet but the power is crazy. I will try and drive it like an old lady to see if the mileage goes up and report back later.
