Default Improving my AF ratio

I've got an AFC Neo, but now that I've had my wideband for a while now I'm really not in a huge hurry to get it put on. Is this really that bad of a factory tune? I know it's a little rich in the last 500rpm or so, but where are all these people making so much power with a tune?

Are you even in gear? or are you reading in kph? 2000RPM at 70 tells me you're not in gear or something.

Looks like it's running pretty rich. I believe optimal power on NA tunes is right around 13:1. I'm sure some tuners can comment on this more accurately.

You get your power by leaning things out. AP1s are notoriously rich from the factory. Lean it out to about 13:1 by redline, some people even go for mid 13's if they are feeling adventurous.

I wouldn't mess with timing (though I don't think the Neo can do this) unless you really know what you're doing. But IMO any schmuck can road tune AFRs, but I have more faith in humanity than some, I think.
