Anyone Break the 300 Mile Tank?
I have gotten 244 miles on my untuned IX. All city driving. It fluctuates from tank to tank badly sometimes, like 220 one time to 170 the next. Thats with trying to drive the same each time!
On a highway trip if I wait for the low fuel light to come on I am over 300 miles when I get to the next gas station.... usually around 12 gallons of fuel at the fill up, anywhere between 24.5 and 25.5 mpg depending on conditions. That gives 320 to 330 mile rage if you want to keep a 1 gal reserve in the tank. This is on my heavily modified EVO making between 550 and 600 crank HP depending on who's correction factor you use (472 on Buschurs Mustang dyno)....

I've never taken mine on a road trip longer than 100 miles or so one way. But before I modded the car I got 22.9 mpg every time I checked, which was almost every fill-up...I fill up as soon as the light comes on, so that was about 280-290 miles per tank, filling up 12.5 gallons. Broke 300 several times; the most I ever got was 321 miles.
Since I finished modding and got tuned (Buschur Stage IV, 20G-IX @23 psi with a reflash and 272 cams), I'm getting 21.0 mpg, typically 270 miles per tank. With a crapload more HP.
This is all combined city/highway driving, no straight highway drives.

Glad to see you post here Keith about your car.
Here is the deal, please all of you think about it. The factory car will run very very close to 14.7:1 AFR's at any low load condition. This will give very good fuel mileage and you should see about 25 mpg, just as the car is advertised to get. The problem lies when you into boost. The AFR's get EXTREMELY rich very quickly. It is normal to see AFR's in the 10:1 range when in boost on a stock EVO. So if you are driving so the car is hitting boost, climbing hills, changing lanes and accelerating you fuel mileage is going to go down hill very quicly.
A slightly modified EVO that has been reflashed should get significantly better fuel mileage than a bone stock car. A full turbo back, air filter and a re-flash could honestly pay for itself in fuel mileage IF YOU DON'T BEAT ON THE CAR FROM BEING ADDICTED TO THE HORSEPOWER! HAHA
The very first BR350 car we built, stock cat on the car, 21 psi, reflashed got 28.4 mph.
Trent's car has gone 11.20 at 120 mph, his car with the AEM in it, coming back from the Winged Warrior event got 29.4 mpg. Jarrod's car has gone 131 mph trap speeds and got 27.6 mpg it makes 505 whp. My RS made 590 whp, ran 9.97 at 142.32 mph and has gotten 26 mpg on the highway.
You have to keep the load low (no boost) and drive like you have some sense. The engine is highly efficient. I have customers who have been over 30 mpg with their DSM's and EVO's on the highway. These numbers are from guys that know how to check fuel mileage, fill the tank, run it out, fill the tank and divide the miles driven by the gallons used. Not a guess or half *** fill job.
Great mileage is a tune and self control away

30 + MPG, great, but honestly, I got 22-23 mpg, I am happy with it, performance and all, what's wrong with 22 mpg, not a bad gas mileage at all, better than SUVs or many other cars on the road today.
Once I heard a comment about MINI Cooper S, "What? you only get 26 mpg", hello, 26 isn't bad, better than the gas milage on your mini van, and the EVO and cooper S can blow your sliding doors off anytime, if I want good gas mileage, I wouldn't go buy an EVO, I would be driving a Civic hybrid.
