Not necessarily. Several members have this alot with the aeroforce. The aeroforce tends to stay as a standard gauge and only used for certain things and this is used on the fly for everything, plus it doubles as a code scanner which is a nice bonus. Unless you have deep pockets and just want a standard scan tool this is worth its weight in gold. I spend $17 on mine, took a risk on a cheap one from Ebay and it works fine for me (I always have the shops scanner as a backup) but most recommend a solid one from Amazon or the really nice $75 +/- kiwi one. Just up to you. Even with the kiwi its cheaper than most scanners due to all the info it gives, plus it has additional plugins on the market that make is so worth it.
Track recorder is my favorite.

Why bother? Unless you have an intercooler the heat in the supercharger is going to offset anything you save on temps by building/buying a cold air intake. If it were me, I would worry more about getting more air into the motor than I would colder air, I know colder is denser but until you get to big power mods the smidgen of extra power made by colder air is negligible.
