Yesterday I installed the Steeda CAI, removed the hydrocarbon trap, and flashed the computer with a SCT tune from Steeda. Steeda says it gives you 20 some HP, hummm I don't know because I don't have before and after dyno pulls. The nearest dyno to me that I know of is 700 miles away. Anyways, the moter feels good and from a "seat of the pants" point of view it's awesome. It's a big difference in motor response. Step on the gas and things happen right now as opposed to before happening in a second or two. On start up it seems to idle (1100 RPM) a little high, then drops around 850-900 RMP range. I'm not sure if that normal or not with this tune, I'm going to call Steeda and ask. Overall and without a dyno to see what I really gained I'd say this was a good buy and the CAI and the flash was very easy to do.
