norcalcrx

did they forget to put it back into closed loop on your tune maybe?

dnbruut

try living in holland its almost 2dolllar for 1 litre regular!

RobbieG35

Lets see, with about 50% highway, and 50% city driving, getting on it about 30% of the time my Si gets about 270 miles to a tank - When it is all the way empty (gas lite staying on), a little over 10 gallons fills it up.

HTDragazn

Mine is a H22 and i do 300miles a tank and its ~12 gal each time i fill up. And a gallon is $3.05 = $36.60 So that is about 25 mile per galon. I'm using 750cc and a Walboro 255lph too. Something is wrong with your tuning 289whp here

Exact same as me in my 00 si.

Civicman86

I got 30mpg (hope to make that go up a little more with some more tuning (10g=300mi).

Oh and I run Open loop 24/7

0xenocron

32-38 mpg...i tuned it myself on Crome really pushing the limit on my own car of 'lean burning' in the part throttle/cruise areas

you should be getting stock or better after a tune on Neptune unless they only did WOT tuning

boostedcivicsir

as long as i stay out of boost, and keep the a/f 13. - 14. ill get 250 +- maybe a little higher on highway. i made it 120 miles from my house to ocean city md on a half a tank this summer for "ricer fest"

PM-Performance

I was getting almost 30mpg in my ITR.

dunkd

i get around 23-25 on all around town driving, beating on it once and awhile too.

Kowalski

Can we refer to it as MPG instead of miles per tank please? I don't think anyone runs their car until they run out of gas.

Thats 27 mpg... Not 270 miles a tank. Your tank has more than 10 gallons.

turbo_ef9

i get about 33-35 to a gallon with my z6, 450cc, uber, 15lbs.. gas here for super is about 3.05 and usually pump when the needle is a lil above the E and i get about 8.5-9gals.. bout 320-330 to a full tank..

deftones0817

25-27 mpg on a b18c1 crx with 1000 cc injectors daily driven. I could get more but I didnt have time to tune it alot lately.

i see that around town as well, and maybe 25-27 on the highway because my ls is screamin at 4200 at only 80mph

nonvtecD

I used to get low 30's but this summer I have gotten nothing but crappy mileage in the high 20's

Sprockets

iTrader: (6)

I usually get &lt;25mpg. I'm curious how much fuel is burned because of the turbo timer.

Sure, but your roads are better, and public transportation is the best in the world, as are the bike paths. Plus, there are other "benefits" to living there.

Boostage

People if you wanna get better gas mileage look into water injection systems and retune your car.

tony n.

damn, well my **** fuked up then...

WTF does water injection have to do with part throttle fuel fuel comsumption?

To the original poster, the problem is most likley your tune. Your tuner probably didn't even touch the higher vacume columns of the fuel maps.

turtle-eg

I have the same problem... but I haven't really tune part-throttle yet.... I get about 120 to the tank with mixed driving(dyno tunned WOT only).

I used to get 250+ to the tank with my street tune.

tony n.

so its my tune right?

dunkd

yah tune is probably extremely rich. was it tuned on the street with a wideband as well as the dyno?
