That is ONLY correct if you drive WOT all the time. But if you cruise, then the AFR will be at 14.7:1 regardless if the car is tuned or not. So the mileage is not affected. Get two Evos one tuned and one w/o a tune and cruise in them on the freeway and check the mileage. It will be the same for both.

 

wow, really... my evo gets ~17 so ur sayin with a tune, my mpg won't change at all? that's sad...

 

I only get 200 miles per tank! What am I doing wrong, haha. Thats normal crusing around town, always in 5th or 6th.

 

Same here, around 200 miles per tank, with "normal" driving around town. Car is bone stock.

 

I've gotten 306 out of a tank before and still had atleast a gallon left in the tank. On average, I get about 220-230 or so per tank.

 

I get 300 per tank with half highway , half secondary roads . Hardly any lights or stop signs . Just a drop-in and a cat-back for mods . I always boost getting on the highway , I take it pretty easy otherwise especially with my daughter in the car .

 

I averaged 28 mpg on 200 mile highway drive. Tuned car with basically a stage 3/4.

 

im at 250 only mod is a reflash from jestr..
gas prices r killa right now

 

Thats about right your getting alot

 

I average 17mpg. During track days I get 6.5mpg. There must be a gas leak somewhere...

 

You do have to realize we only have 13 Gallon Tanks, so saying I only get 250 per tank and complaining about bad gas mileage might not be accurate.. you need to figure out the Gallon to mile ratio. simply see how many miles you get and divide the the number of gallons you have. Can someone clarify do we have 12 or 13 gallon tanks I always forget.

 

im usually in the 250 - 260 range per tank

 

per tank means nothing, let's see MPG numbers it's not that freaking hard guys.

 

I get 23 or so when I drive very mellow.

 

I think our tank is 14 gallons since we do not have the AYC. I have put 13.4 gallons in once. i always fill up when the light comes on. 20-21mpg city
