EASY..............ram more air in there

 

Haha, Kris sportin the new screen name!

 

so a larger intake manifold and throttle body would cover that, right?

 

he's talking in the form of a 'snail',

 

ooooh i see... LOL
over my head

 

First off how do you know that you are running rich?
what are you modifications?

 

no im just asking, so i know what to do or say. trying to understand about fuel management and other stuff.

 

I do know for a fact, that stock, 420A powered Eclipses and Talon run super rich from the factory.

 

any unmetered sorce of air will help you not run so rich.

At the least you need a a/f guage to give you some sort of idea on whether your rich or lean.
Then you can always step up to a egt guage and a s-afc to fine tune your car for a perfect air/fuel mixture.

 

you need the AEM UEGO wideband O2 sensor to really get a good A/F reading... the Stock O2 sensor is worthless for tuning, and the AF guages read off the stocker... and thats a 0-1v range... narrowband. wideband reads from 0-5v, so its pretty accurate. WB 02's are expensive though, its sophisticated shizzle, stuff that MKIV supra guys use.

you could also check it on a dyno and use the WB o2 sensor on there.

the beleif that Neons, 2GNT's, and DSM run rich from the factory doesnt really give you much room to work with... its just a safety net built in, not enough of a margin for you to be tryin to bump the power on the stock fuel system... Returnless fuel ssytems are a joke, and cant flow enough fuel to support big power.

anywho... WB 02 is the way to go, like DIY-WBO2 or the AEM UEGO.

Oh, and a bigger TB and Intake manifold arent really the best way to get more airflow. more boost is the best way, within reason.
