Because of a possible "lean running" problem, if you have a 2004 or 2005 truck, you're better off not using the CAI. Using the stock intake or the "Gotts Mod" intake is a much safer (and probably more productive route). The 87 tow tune is a very good all-around tune, and it's what I used until I got my custom tunes.
