Some of the cold air intakes out there for example don't require a tune and some do. I can tell you that's because they are about the same exact size tubing wise as the stock intake system. That is a FACT. It's not pulling anymore air than stock, or at least not enough, to need a tune. The other ones that do need one, are actually pulling more in which is too much for the computer to take in, where as it does need a tune.

So please don't go with a CAI in the end that says there's no tune required.
