It should be good to go, Speed Inc does great work especially with FI. I`ve heard from most that 11.5 is good w/FI 12.0 is on the limit so I guess 12.5 would be too lean for FI.
yep, 11.0-11.5 is a good place to be, at the track with good gas I have ran to 12.5 but thats pushing it - makes good power but no room for error. Most in car widebands arent the most accurate things either so it never hurts to hook up an EGT if you are pushing it.

I would say to some extent depends on where you live and in how many different conditions you drive your car in. 
If it gets cold, say around freezing start with something rich 11-11.5 AFR. But then if you live in hot climate that doesn’t get too cold, I would think 11.5-12.1 may be fine.
More then one FI engine has gone too lean on a cold day.

Dont have to worry about cold weather here in Orlando for a long time, but then again by the time Mike Norris gets Jeff`s and my motor done it might be winter again.
