Nope. Pull the negative terminal during installation, install the intake, put everything back together, let the car idle for 10 minutes with the a/c off, then 5 minutes with the a/c on and enjoy. Car will behave just like it did before the intake, with the exception of a noticeable loss of streetable power.
You only need to tune when adding forced induction, changing the maf housing size or location, or various electronics systems.
Again, no tune is required when adding the boss intake manifold when it is mated to the factory intake tube. If you have a aftermarket "tune required" CAI, then you already have a tune, so no update is required. Simply up the rev limiter to take advantage of the right shift in the power band.

No, you don't. I can swap between the two intakes on the same tune. I can add longtubes on the same tune. I can swap pulleys the same tune. I can spray a dry shot on the same tune. The AFR will always stay in check as long as you have enough fuel available.
