If your going turbo then doing a complete trans upgrade is suggested.

It's not hp that you need to be concerned with on the auto, it's torque. Over 400ft-lbs and you're going to have issues in the upper gears. Of course, the Stillen kit not only won't make that amount of torque, but also it'll kindly grenade your motor to preserve transmission life.
