There are a few people that have indicated that they are getting Bank 0 and Bank 1 Lean codes. From what I have seen, this is always in conjunction with a CAI. Some are less sensitive that others, such as the AF1, and can run fine with the Evo. However, most of the trucks with CAI's (especially those with modified exhaust as well) would do better to have the calibrations tuned to match the setup. Not only will the truck perform better, but more importantly this will avoid any lean conditions which could adversely effect engine durability. (Read that as avoid screwing up your engine!)
Hoe this helps.

I just spoke with Mike Mc something at Troyers and he said I should be fine but maybe heave my air/fuel checked at a dyno if I'm really concerned about it. He also said it would kick a code if I'm too lean.

Then I called Edge and their tech guy told me that the design was intended for stock parameters. He wouldn't say a whole lot when I question the cai, exhaust combo w/the Evo and the possibilities of lean conditions.
I really do appreciate everyone who has chimmed in but now I think I'm going a different direction. The whole lean thing and possible engine problems just isn't really sitting well with me.
Summit Racing hooked me up with Akron Horsepower www.akronhorsepower.com. 85 bucks for three pulls on the dyno. Their big time into the 'Stangs and seem to know the what their talking about.
Long story short, I'm searching threads now to learn about the SCT Livewire. He told me to stop down and he would show me dyno results with this showing close to 50hp gains on the f150!!!!!

I actually put in a air fuel gauge in that fluctuates alot up and down. it will sometimes read lean for a brief time say 10 or 15 seconds before fluctuating back up. I have never thrown a code.

Dang, screw the Evo. I want a better picture of the "toy" cabinet!! 
Anyway...
Yes, the Evo can be custom tuned.
Yes, you should ideally do a dyno run to check your AFR.
At some point I am going to have to convince Edge that they REALLY NEED some sort of simple AFR monitor. The problem is that the narrow band O2 sensor used on production vehicles doesn't work all that well as a pinpoint AFR monitor. It is basically used to count Rich/Leam transitions to determine if the engine is running at the target AFR.
Still, some sort of display could be useful. If the thing was always lean, you'd notice a trend and then could take steps to alleviate it.
One thing to keep in mind is that the ECM is always going to try to achieve a specific calculated AFR based on the amount of air ingested. Any changes to the way the Mass Air Meter (MAF) calculates air intake is going to throw off your AFR... PERIOD! This is why the Evo (and most other programmers) works fine until you change the intake tube. After that (in most cases) the MAF is no longer accurately representing the amount of air going into the engine and subsequent lean conditions result. Some units such as the AF1 are less troublesome in this area and can run quite well with a "canned" calibration. Others don't fare so well and usually require a bit of custom tuning to help keep the AFR in line.
I hope this helps.
