"You" don't tune it with the tuner, you simply use the tuner to load pre-written tunes. The tuner doesn't allow you to access those parameters of the PCM's tune that relate to performance. Folks like AM, Brenspeed and others that have the license rights can write the tunes. SCT is more widely used. Have you researched the CAI & tune combo's on the AM and Brenspeed websites? Their tunes are some of the better custom tunes.
