get a custom/openecu tune specifically for your mods or get rid of your CAI and BOV. Custom tune would be the best way to go.
Bugeye Wagon with a P&P TD04, catback, Bullwinkle Tune, I get low 20s... even lower now with the stupid Ethanol in the gas...
This, but also consider that the temperatures outside have an effect as well. You say you just bought the car in Sept, right? I've been recording my mileages for almost two years and I've been hitting the high numbers from May-Sept only. My car really likes 60-70 degree weather.
This is partially true. A car with an intake that is a different size then stock could certainly get poor gas mileage due to a poor tune. However, for most cars with typical mods, most custom tunes work specifically on the high throttle and WOT areas. Personally, I don't change much of the cruise timing areas, as I simply do not have enough time when doing a 2 hour tune. As a result, I tell folks that gas mileage will be similar to stock after the tune. In reality, most changes in gas mileage are due to weather changes, driving style changes, and ethanol content in your fuel. For what it's worth, 06 WRX has gotten about the same gas mileage at every point in its life. Around 22-24 MPG in the summer, and 18-20 in the winter. I do primarily city driving (trips less then 10 miles).
97 GF wagon EJ22, weapon R intake, aftermarket muffler, 30-32mpg hwy in the summer and about 25-27 city depending on how you drive it.
You need to get that looked at. Seriously! I have never got that bad of gas mileage. Even when making bismark to fargo in under 2 hours.
2011 WRX, VF52, E85, 16MPG, Mixed Driving (Mostly City) I got 19MPG on my last tank which was nearly all highway miles. I got between 20-21MPG with mixed driving when I was on 93 octane.
Looks about right. Also looks about right. And for the e85 guys, figure 30% worse mileage than same/similar setups. Take SkeetsWisconny's numbers and pull 30% off and everyone is right around that same area. Russ
I track my fuel fillups pretty religiously with my GPS. over the last 10k miles (since I got the car), I've averaged 28mpg, best of 38.4. http://www.fuelly.com/driver/numbchux/celica That's in my '92 Toyota Celica ST. 1.6L Automatic. Running MASSIVELY oversized (almost 3" taller than stock) blizzaks all winter.
I usually average about 18-19 anytime of the year with mostly city driving on my 02 RS Auto. I got 24 once coming home from school (all freeway miles with no stops
I got 25 mpg in the tribeca on my trip to colorado, it was crazy to see the display say 610 miles till empty, when we filled up. Otherwise she gets about 19-21.
20-22 all winter (bought it in Dec) now up to 23-26 since the weather warmed up some. 04 STi, pretty well stock. SPT intake, AP stage 2 tune, NOT a light foot.
Because now the motor is running more efficeintly and creating more TQ, so the motor does not have to work as hard to keep the car moving forward. It is like drafting, but different. The less load that is placed on the motor, the less fuel it will use. If the motor can efficiently use the fuel it is provided (IE not wasting it), you will not have to press the pedal down as far to keep the car moving at speed. With drafting, you have less load on the motor because you are not pushing as much air around the front of the car. Russ
Back when I had my 02 WRX, the best I ever got on a tank was about 31. The worst was 8. My average was about 20-25. Frustratingly, the 1.8L CVT Versa I had later got about the same mpg as the WRX (you had to wind that sucker out or it felt like an arthritic snail), and now my 8-passenger Toyota Sienna gets about the same again...
Thought I should check in here...14-14.5mpg over the last few tanks. Not too bad for money:fun ratio imo.
Pretty sure that's what I'm averaging as well. Obviously a HUGE difference with how you drive. Multiple redline pulls and you can immediately see the fuel gauge lower than it was. Cruise control at 2-2.5k rpms and it'll go quite a while. WELL WORTH IT!
