probably more aggressive driving lol

But I sense that the car runs more rich after header install so thats fuel wasted..

Track duty is around 5 mpg. Mostly city is 16 mpg. Mostly highway is 20 to 21. Pure highway (long distance driving) is 27 mpg. Right now I'm in the 16 mpg zone because my commute is mostly city.

Im usually averaging around 16.5 mpgs overall. I did a lot of highway driving this weekend and was blown away to see 21 mpg. Thats the best I have ever seen. Im sure the run with the clown in the SRT4 didnt help. ( had to take him to F school)

My tank average since buying my f is 22.4MPG. I have had it up as high as 32MPG on a long motorway run.

This is a mixture of city driving and motorway runs.
