How to go from 23mpg Highway to 29mpg
I love all the responses to posts like these saying people are liars or don't know how to add... I'll use the same post I did over at the other EvoX site, seems there are even more **** slingers over here. There are plenty of people getting 24-25 mpg on the highway, how difficult is it to believe that getting 2-3 above that is impossible with the right combination of driving style, tune, and modifications? if you drive full throttle at every opportunity then of course mileage is going to suffer. 
On my trip to the 2009 Buschur Shootout I was averaging 70 mph and went 350 miles with 13 gallons used which is just about 27 mpg, while my dash read at 28.x something. Sure the dash MPG estimate is always a bit optimistic but if I reset it on a flat highway at 70 mph with cruise going it does calculate real time usage at 30-31 mpg consistantly and if I actually drove an entire trip like a total ***** I would expect to get 28-29 mpg overall.
So while I don't trust it 100% it still gives you a rough idea of where you are at, around town during normal work weeks it still averages low to mid 20's. If I'm testing a new tune you can throw the MPG contests out the window as I'm lucky if I hit 20 mpg...
Much has to do with the way you drive the car, I get 7 mpg at the track but if you tune the lower load cells (0-70%) at cruise with ~3* higher timing you can gain MPG and if you have a larger turbo that allows your entire engine to operate more efficiently and not instantly jump into boost at light throttle you will gain MPG. AFR's during spool and MIVEC tune also have an impact of how much fuel is being used.
I will be keeping carefull logs during the One Lap of America trip as well, the only difference being that it will have an extra ~500 lbs of weight in it with an extra driver and gear when not on the track.

Also, FWIW, I never questioned you, Highboost; you had the proof and the research and the tuning to back up your claims.
It's the random, usually mis-spelled, usually **** poor grammar posts of "O ya I gte 31mpg r u doing soemthing rong?" posts that **** me off.

just to add fuel to the fire... I can regularly get 25mpg on my trip to/from work... 27 miles each leg, combination of rural highways with no less than a dozen stop lights. Takes about 50 minutes on average (avg. speed of 30mph) so I am definitely not cruising by any means.
It's all about driving style (read: engine braking). Every time you apply the brake pedal, you are in effect, wasting gas.
My car has intake with AMSOil filter, IC pipes, and turboback (with HFC), however I am completely untuned. In addition to leaning out the stock tune, there are other ECU changes you can make to assist with fuel economy (there is a thread about it somewhere in the Engine Mgmt forum).

You can go to the options and turn it from Auto to Manual and it will pull in the values from the last Reset, BUT the next time you shut the car off, it automatically returns to Auto again. That is the dumbest feature I've seen yet.

1.) you drive like a woman ALWAYS
2.) You are a big fat liar
3.) your car is a "Sally", and should have been born a prius

i try to get the mpg up in city driving by letting off the gas and "coasting" to the red light. i usually avg 17-19mpg on my way to work. it's an MR so it's not really coasting, but i use to do it all the time on my last car that was a manual. i know it's dangerous, but really, if there's a red light and you have 100 meters in front of you what are the chances you need to punch the gas instead of the brakes?
I think is a great topic. Because this the same question I have been wondering as well. I drive like a granny and still the best I get is 215 miles on a full tank of gas w/ AP stage 1 reflash. I even put it in neutral on downhills.
My girlfriends 08 Lancer is also horrible with gas . It is also a 4B11 but obviously higher compression , Fwd and no turbo but it still gets from 14-24 Mpg . I have even seen it at 11mpg in traffic . I think its more attributed to the weight of the newer gen Lancer/Evo more then anything else , her car weights 900 Lbs more then mine and i get about 35mpg .
you are better off leaving it in gear. when in neutral, gas is used to keep the engine idling. when in gear, inertia keeps the engine rotating and there is no gas used....
