Another thing is DFCO (Deceleration Fuel Cutoff) in the tune, I see some tuners turn this off, and I have played with mine and lost about 2mpg when driving through town a lot with it off. There are a lot of factors that can cause MPG changes so I would not be too concerned.
I can say though my MPG got better after my mods, but I don't have headers yet, but I cant see it causing a MPG decrease really.

It's normal. Enjoy your car. If you're worried about MPGs you; A) need to buy a Prius and B) stop modding |

I just installed headers, and got the car dyno tuned, the car runs great.. I couldn't be happier. As far as mileage is concerned.. One I figured out how to change the display I stopped caring, not that I did before I changed it.. lol

Worse fuel mileage because you can't keep your foot out of it, It's just too much fun!

I have a JRE tune. I have not reset the mpg in a year or so and displaying 17.6. It used to be exactly 16 before headers and tune. I guess Jannetty is a magic tuner. I tend to have a lead foot too
