Tuner results for MPG'S

[RAMthis2004]

I'm looking into getting a tuner for fuel economy... and it's for 4.7L. Reviews, results, thoughts? Only add on my truck is a CAI, with an exhaust sometime in the future.

Your best bet is to go with a Superchips Flashpaq. Most guys see about a 1.5mpg increase in fuel mileage as well as a nice bump in power.

Is there a difference between the Superchips Flashpaq and Mileage XS tuners?

I have the 3865 Flashpaq. I started with the Mileage XS tune. It gained me 2 mpg. I went from 12.5 to 14.5. I recently switched to 87 octane tune and noticed much better performance, better throttle response and better shifting. Not sure what the difference is between the tunes but my fuel mileage hasn't changed. I think I even get better mileage on the highway with the 87 octane tune.
