uummmmmm i dont think you can...perhaps you can crank up the fuel pressure but if your pcm is operating properly it will take over and adjust for a 14.7 ratio depending on o2 sensor inputs
and why do you wanna change it ????

Probably make it worse - may richen the mix to compensate for colder temp.

Sorry...
A 160 will make it run richer! I assumed you needed fuel to compensate for mods.
1. Are you rich all the time or just at idle?
2. What is the voltage reading from the O2 sensor?
3. Are the readings taken with your air filter and intake system attached?
4. What is your water temperature?

it only reads rich when it is at wot
what wire should i get a voltage reading from ther are 4 wires 2 white a grey and black the air 2 fuel is hooked up 2 the black
i don't have the stock air filter set up i have a edelbrock air cleaner but i think that would help it run lean because of more air
i have a 180 stat in it and the stock gauge say it is normal so l don't know how hot is gets

You get the voltage reading from the same black wire. The Air2Fuel guage is basically a voltmeter. How many lights does your O2 meter have and how many are lit at WOT?
The more air theory is correct but the air is hotter so the charge may actually have less O2 than a filter system pulling air from in front of the radiator.
You may actually not be burning the the fuel completely! Is your ignition system in good shape?
Are your injectors clean? A poor spray pattern can cause similar problems.
Just a couple of ideas! Come on Dak guys, give us some input. I feel like the lone ranger here! I'm not a Dak guy by trade, I'm still learning too.

the gauge reads all the way rich at wot i will have 2 check the voltage when i get time i think the spark is good cuz it runs i put some injector cleaner in and what voltage should the o2 be at
