Hmm...I'm not so sure it would though. Well, let me phrase that a little differently. It depends on whether or not the canned map properly takes into account all these mods that causing people's cars to run lean. I'll be very interested to see your results. It should settle this particular question once and for all. I certainly hope it takes care of the AFR. Less hassle/effort/expense for those who are just looking to correct their AFR!

Semtex is right, they have to do two (or more usually) runs.
The first run will be getting my current baseline numbers, AF ratio, etc. Then they will start to do more runs smoothing everything out and making adjustments as needed.

I can't speak for Cobb, but I can tell you that when you reflash the new ROM into your ECU with UpRev, that base map is exactly that. It's a base map that has all of the factory parameters, and assumes no mods. By itself, it is not intended to yield any gains. Its sole purpose is to provide the tuner with a platform on which he can load maps that he builds via the process of running your car on the dyno. You see, the factory ROM that comes from Nissan allows no such thing. There are no 'slots' to drop the maps you build into, so to speak. So you replace the factory ROM with UpRev's ROM, and their ROM has these 'slots' for you to plug your performance map(s) into (as well as your valet and anti-theft maps).

But you can also use Cobb to do a full dyno tune. And if you were to do that, I suspect it'd work in much the same way as Uprev. i.e., the initial load would be a 'blank' map that has all the same parameters as a stock car. It'd be kinda like a blank canvas onto which your dyno tuner could lay down his masterpiece.

so to find if Im running lean right now, what gear and rpm range should I do a AFR check in? I have the 7AT.

Doesn't Cobb log the data as you run through all the gears? Like it doesn't require you to stay in just one gear while you log, does it?

quick question since we're on the subject, the software that came with my AP doesnt allow me to view my maps or alter them, its some kind of crazy format, any ideas on what software I should download to view them?

I think Cobb has a tuners software program you can buy to do that.

Hmm...Well, if you think of a dyno graph, AFR is measured throughout the entire RPM range. So I would expect Cobb to do the same thing. But you might have to stay in a particular gear, just like you dyno in a particular gear. On the 7AT, I think you're supposed to dyno in 6th.

You would think that it would come with the hardware...
