BodyGyro causes character to spin uncontrollably?

Not a serious scripting question, but I added a bodygyro to the player's character to turn him towards a certain direction, and the bodygyro changes cframes so the character turns towards different directions. The problem is that the character would either jitter (I believe when P is too close to D), or spin uncontrollably (when P is way bigger than D). Anyone have any experience with and can provide assistance in this situation?
