MPG didn't change on me from all stock to a UEL header and modified OFT tune. 20 MPG is average now(18 mpg if I drive like a maniac) but that is all city and very short trips.
Taking it easy, I can squeeze out 25 MPG, again with all short city trips. 90% of the time, it's a 5 min. trip or less. On highway and driving normal, it gets back up into the low thirties.
