If you are overboosting, then why do you want a boost controller? All they do is regulate the boost pressure going to the wastegate actuator, allowing you to boost higher. You can't "turn down" the boost pressure a turbo creates by adding a boost controller.
It sounds to me like maybe your wastegate is not opening either enough or at all. Is the vacuum line connected to the actuator? Is your downpipe interfering with the movement of the wastegate?
