I have the SC 3865 Tuner and I've ran the Mileage XS Tune for a good three weeks (approx. 4-5 tanks). My mileage was less on the Mileage XS Tune than when I ran stock or the 87 Octane Tune. It went down a good 1.5-2 mpg's. My driving didn't change any and I actually get as good or better when I run the Performance Tune too.

It detunes the pcm to where the engine has to labor to do what it needs to do, which in turn, uses more fuel. Mine does best on the 93 octane setting on my Predator.
I drive about 72 miles round trip to work and will be trying more things to increase mileage. Currently, I have a K&N drop-in filter, Airaid MIT, Magnaflow cat-back and a Diablosport Predator. The Predator made the most noticeable difference in power and MPG. If I turn the MDS on, I can get 22mpg+ on fairly level ground at 65mph, but it sounds funky
I found 1 easy way to increase my mileage this week from 18 to 32.
I drove the wife's Caliber to work all week
