Car runs a little lean (I want richer AFRs)

So my car always runs on the little bit of the leaner side. I have logged time and time again, 93oct with and without meth, and e85 with and without meth as well. The car has shown no ill effects, but would like the car to be just a tad richer.
The question is how does one go about changing this ratios? At one point I thought changing the ol fueling would change this, but after doing so and plenty of research, i have found and learned that this will not change my AFRs.

Any insight will be greatly appreciated.

Hello - why do you want to run richer if you are seeing no ill effects currently?? It'll just be a waste of fuel...

Just block all the air intake areas so you only run on gas, that'll be cool. But no air = no fire.

Random thought since I don't know about AFR's, would a strict air intake (lesser air) coming through make you run rich? I am a noob to this kind of stuff.

you need to modify the AFR targets in the procede. Ask shiv to help you out.

Enrita, I was going too, but figured someone might be able to give me a little advise on how to do this myself.

I have put alot of thought into my AFRs ever since you brought up how lean they looked last week. The vishnu "read me" file says i am within spec, but after looking at countless logs from other people I clearly see that Im anywhere from 0.5-1 point leaner than most.

Yes, just dropping the two files in your Procede folder and saying yes to replacing older files with the same name.
