There are some CAI that require no tune. I have the Granatelli CAI which came in with its own MAF sensor and required no tune. Designed to run on 87 octane. I had no issues whatsoever.

However, about a month later, I decided to get the SCT X3 tuner and tunes from Brenspeed (same CAI). Many here will tell you that a Stang with a tune runs different (=better) that one without...guess what? They are absolutely right. BTW, I experienced to difference running the stang while in no-tune mode.
