Im getting pretty bad mpg i think i filled up and i was down to less then a 1/4 of a tank i had only driven 120 miles? i wasnt killing it on the gas pedel eather

 

Do u mean like 1/4 left, or only used a 1/4. Cuz I get like 80 miles to the first quarter of the tank

 

Clutch may be going.

 

welcome to en evo.

on pure city driving i will get 110-120 miles per 3/4 tank.

 

Wtf :/ Haha free way driving ? I'm jealous. I get like 200-240 a tank..

 

Are u tuned?

 

Wait... Wait... let em answer. So which is it Vinnieq, 1/4 used or 1/4 left?

 

i filled up went 12o miles and had only 1/4 tank left

 

"down to less then a 1/4 of a tank"...i don't think he would be complaining about 120 miles for 25% fuel burned.

 

I get about 180-200 per tank tuned

 

I assume youre on pump? It could a problem with your tune. Have your tuner check your maps out.

 

for city driving i dont think it will be much better...ive tried a lot of map work. last thing left is a new front o2, but im over it at this point.

welcome to driving a high performance car.

 

Is the CEL on?

 

Calculate your fuel usage in GALLONS per MILE if you want ANY sort of accuracy. A MPG shift that seems very significant can actually only be a very minor change which can be attributed to weather.

Have you checked the common things like, what do your plugs look like, boost leaks, etc.?

 

Compared to my 04 STi, it's way harder to drive this car off boost. And once you've dipped into the boost, forget about MPGs...
