im averaging 19 mpg mostly city driving 12 miles one way to work. thats with me mashing the pedal quite often. way too easy to do.

I'm glad I'm not the only one that can't reach the 26 MPG mark. LOL. Here in New Mexico the speed limit on the highway is usually 65-75, so of course I'm almost always doing 80. I'll try going 65, and see if I can hit 26 MPG. Around the city, I drive it like I stole it, so my mileage is garbage.

The best fuel mileage will be about 70 mph with 3.31:1rear gears, maybe 65-70 for 3.55:1 and maybe 65 for 3.73:1.

With 3.55:1 and 3.73:1, my guesses exact peak fuel economy speeds might be wrong but going with deeper rear gears will sacrifice your fuel mileage

I was able to get 24 mpg today on the highway doing 60mph until I drove into a nasty head wind that decreased that to 22.

I hear you. Driving into the wind will destroy you mpg very quickly. But when you have a tailwind and you are cruising along at 70 mpg you begin to get hypermiling mileage. Getting 28 mpg avg on straight flat freeway with a strong tailwind allows you to cruise while barely sipping on fuel

Yep... Took a trip last month.
Memphis to Little Rock, sightly downhill into a strong wind. 23.3mpg
Two days later on the return trip, slightly uphill and with the wind 26.7mpg

60 mph = 27-29 mpg in mine.
Steeda agressive tune and intake.
I average 23 plus.

Drove he last 100 miles strictly in city stop and go, barely any freeway, and I am down to 22.5 MPG avg, but I have not reset the MPG counter for the last 300 miles, so the higher number from those previous miles might have mitigated the MPG loss by being averaged in altogether.

I know a tune helps mpg, but by how much. What were you all getting when stock?

JIM5.0

Over stock, I can see probably about 2-3 MPG avg more. Considering that you are looking at a 20 MPG avg overall (mix of hwy & city), that 2-3 MPG avg increase is significant; that translates into 10-15% above stock tune.
