Well, any fuel management for that mater..

I used to get 210 miles to a tank
Now I get 240 miles to a tank.. nice...

Mid and Top end power is great!!!

I also played with the LO settings and put -1% all the way to 4000 RPM. so at 65mph no boost, I have 1% correction (even on idle). it also eliminated the bog when releasing the clutch at 1200 rpm traffic stops... I wish I have a wide band so I can tune the LO settings to be stoich at 65 MPH..

Helix down pipe (3 inch), stock cat, HKS cat back, Greddy intercooler...

I'll dyno soon when gruppe-s has there dyno up and running..

 

210 miles to a tank.??? i just got 295 last week... stock....

 

What did you do, push it for 50 miles??? I am getting about 245~250 with an HKS intake. I just installed my afc and don't have solid numbers for mpg yet, but it sure did increase the pull on the high rpms per my butt dyno.

 

Damn!!! 295 a tank!!!! that would be a record!!! When I get 215 before, I would treat my friends to lunch. But 295!! Daaaammmnnnn!!

 

im serious... no lie.... anyone think im running lean???? i still think im running on the rich side cause i have to clean my exhaust off all the time cause it gets really black....

 

I get between 180 and 230, only once I got 250
The only way I can see you get 300 is if you drive long distance highway miles, no boost or if you did some AFR tuning.

 

actually, if you dirve your car nicely without ever going over 55 mph, excessively pressing on the accelerator, you can see over 300 mpg. honest to god, i've gotten 300 on only approximately 13.4 gallons of fuel.

 

Hmmm true I guess.. but where is the fun in that.. I'll try your advice.. 55 mph ey... we'll see what i get.. cheers

 

btw, i'm also shifting at 2500 rpm... nothing more than that. no fun, but you'll save on gas.

 

i shift like 4k in 1st and 2nd and then 3k into 3rd and im in 5th by 45mph...

yeah something like that...

 

I drive my evo hard.. so no fuel economy for me. but what the heck.. i'll try to drive conservatively this week.

 

I drove my evo 2200 miles this weekend, and averaged about 305 per tank (out of six tanks) That was playing on the freewayfrom about 85-90mph average, with the occasional jump to 120. I'm a little bit away from stock.

 

just got back today from vacation... i averaged 288/290 a tank.... full car also.

 

The car will run at stoichometric air fuel at all steady state cruising speeds if you have a stock car and/or stock ecu. You can't make it run any different unless you pull out so much fuel with an AFC that they stock ecu can't compensate with its closed loop fuel trims. You would have to pull out 10% to 20% fuel to do this on the low throttle settings, maybe even more that 20%. The stock computer can do alot of adjustment with its fuel trim. The stock O2 sensor is used for air/fuel feedback at all lite throttle application, that is the reason it works like this.

BTW, to get good gas mileage the other people are right, take it easy on the boost and drive smootly with as lite of acceleration as possible. No fun, but good mpg.

damn..i wish i got 290 to a tank....i cant even crack 200....and thats not beating on it either...something has got to be wrong here
