Well there's 2 things, there's the ProCal software and the tune. While the software will tell you if there's an update to the ProCal software, I think the only way to tell if there's an update to the tune is to download it and compare or call and ask Ford Performance. Unless someone knows another way?
Well, when was the last time they updated the software and not the tune or the tune and not the software?
1) You're always losing with the stock IC. If you're not doing long pulls through several gears you likely will never notice the difference though, it depends how much money you want to spend and how much hassle you're willing to deal with if you want to do it yourself - getting the bumper off is the worst part but there are lots of good guides.
I already had an aftermarket FMIC. There are benefits even for the stock engine. Especially in very warm areas like you are in. When the intake/charge air is that hot, the computer has to retard the timing to protect from detonation, that robs you of power. Cooling the air does 2 things, allows you to run more advanced timing and also provides a larger quantity of air to burn because cooler air is more dense. There is effectively more burnable air in the same confined space if it is cooler. As mentioned, the difference is mostly noted when you're doing longer pulls through multiple gears. Even an aftermarket FMIC will heat soak, they can recover from it more quickly so longer pulls are more noticeable.
I did not get an aftermarket IC... never seen a need. If I were taking it on a track I would.
