Yup, initially dropped about 3.5 MPG overall (I drive about 95% highway at 70MPH). Tuner brought it back up 2 MPG. More importantly than MPG to me, I noticed quite a power difference. I have 3.55 gears for reference. The power was there when I stomped on it, but otherwise seemed a little sluggish. Also, the shift points were significantly off. Driving down the highway and it would often shift from 6th to 5th and back. Tuner corrected all of that and then some.
