Tuning Question---Eliminating 550's 18% over the 450's

[EclipseTrbo420A]

Right now I have many long trips back and forth to college and want the Gas mileage I would normally get. My question is if I Lean out my S-afc -18% across the low and high setting and run my 14B at its stock boost level would that increase my gas mileage. Mods are in my profile and I have a minor tune on the car now. Settings are...'

I forgot to add my car wont accept the Logger anymore. One day it just stoped working. I Get a "NO REV" display. and now I dont have time or money to waste on this stuff ill take care of it when I get out of college and get a real car. But what do you think about /\ my option up there ?> think that would do ? even wiht the 255 I sould get better than the 17 mpg im getting now Highway.

and one more thing do those setting look normal for my set up ( if anyone still runs the 14B lemme know ) Thanks

17MPG highway is rough, I just got 27MPG with a mix of city highway and dyno

You could try putting them where they should theoretically be but you never really know without a logger.

I told you, Replace the fuel filter and give me your wheels.

well what if I replaced them with 450's for the time being zero it out and then when I got everything going smooth put them back in with my old settings? anyone else know anything about my first post and its 1032 for the wheels haha and I will replace my fuel filter when I get a chance thanks guys let me know.

Boost level has nothing to do with MPG unless you are getting on it. Stay out of it and you could be at 30 PSI, it wouldn't matter.

Get that logger working. If you can't get the fuel trims right, there is nothing you can do. I can sit here and pull AFC settings out my ass but they would do you no good. You need to set it up for your car, and your car only.

Isn't tunerstein free and doesn't it show fuel trims? Look into the free loggers. Make sure your cable is in good condition and doesn't have any freyed wires.
