This kind of discussion is good so that others can read and research and come to their own conclusion. Basically, there are a number of ways to "mess with" the reading that the computer gets from the MAF. Some MAF manufacturers actually use sample tubes to alter the air flow the MAF sees. In this instance, JET just changes the voltage that the computer sees from the MAF for a given air flow. As Pirate Air explained, the factory tune is on the safe (rich) side and JET tries to get the computer to see less incoming air than is actually being ingested by the engine and the computer compensates by commanding a little less (leaner) fuel. The question lies in how successfully JET actually does this. My experience has been that success is limited. Furthermore, when you combine their electronic "trickery" with additional mods like a CAI, it can further lean out the mixture, potentially causing damage without a proper tune. I think you'll see the safest gains from just running the CAI. I hope my ramblings made sense.</blockquote>
