I would be very interested in some possible explanations for such an increase as well, but that may be something may be something Dyno would need to come in and explain.

I'm not going to guess numbers until I have more data (a 3 mpg increase would be almost 60 extra miles in a tank). But usually when I romp on it during a tank, I get ~15 mpg (~17 if there's a good amount of highway miles). Add about 5 mpg to those numbers for pure casual driving (highway miles push it up even further). Because of the trip back from the tuner, I would have expected around 17 or less depending on how Joe treated her. But I'm easily getting 19-20 mpg since getting the car back, and based on my driving in that time and previous experience, that's a notable increase.
