This statement could not be any closer to the truth. Mine has a 93 tune, 3:73's and a few other mods. In the summer, I average 19mpg. Right now, I'm getting 16mpg. (Cold engine upon start up, prolonged engine idle while your scraping the windshield, etc)

Don't fret, your MPG are normal for this time of the year.

I just took a 100 mile freeway road trip running a Bama performance tune93 octane and I got 25.6 mpg avg. And there was a lot of stop and go too. Leaving town was in the middle of rush hour. And halfway through the trip there was a wreck that slowed freeway traffic to a bumper to bumper dead stop gridlock.

Were it not for these speed killers on the freeway, I would have gotten in excess of 26 mpg avg highway. And that is BETTER than Ford's advertised 26 mpg hwy!

Granted, this is according to my on board dash mpg calculator
