I'm interested in doing some airflow upgrade to my 2011 GT 5.0, and I'm contemplating the Boss intake. The mechanical side of the work is nothing new to me, but the computer side I'm ignorant of. Ford and every other vendor recommends custom calibration, which I'm assuming is going to require an electronic tuning kit and some time on a dyno. I've never gone through the effort to dyno tune and I've never attempted the electronic stuff.

What and how much work should I be expecting for the calibration?
What are the consequences of not doing the dyno and electronics work?

It should be rather painless. You just need a hand-held tuner (AmericanMuscle or Brenspeed are good bets) with the appropriate tunes. You would simply install the Boss manifold, plug the tuner into the OBDII port, and load a tune. No dyno necessary

^What he said.. You'll need a tune.. Any of the big three does email tunes and will do a tunes for life package if you don't have a tuner yet..

I'm hoping that someone puts together a Cobra Jet intake kit.

+1. Hoping AM does.

doesnt it have some mammoth blower on it and its also like 5.4 liter? how would that even work

No .. it looks similar to the 2010 FRPP instake.

Doesn't the Boss intake kill the low end tq?

It's a shorter shot from the manifold to the cylinder, it can't possibly hurt torque enough to notice/care. It allows for higher rpm capability. The big difference is what happense after stock peak hp (right around 6,500 to 6,600 rpm).

Stock, hp drops off quite a bit, but with the Boss intake manifold, hp just hangs there until WELL after 7,000 rpm....and if you're tuning anyway, you're going to have more torque than stock....

After a bit more searching, you are correct, if you keep the RPMs very high this is a good intake but low end tq suffers pretty good. So for track racing I can see this is a very good thing as you would want to keep the RPMs up all the time. For the street, no so much.
