Driving around town will result in similar gas mileage.

Going wide open throttle, different story. But then again, who cares about gas mileage at Wide open throttle?

Most people who have experienced gas mileage to be worse with a chip/tune is because they tend to be wanting the need for more power and feeling the power so they start getting a lead foot.

I recall some tunes actually increasing gas mileage around town.
