I want to change the settings on my stall converter to lock at the speeds listed below and unlock at 30% power. What do I need to adjust in HP tuner to do this. Right now my stall only locks up in 6th gear and unlocks at full power. When I drive in traffic in Houston temps my trans temps are going through the roof because my stall is always slipping. The trans is a 6L80
3rd-30mph
4th-40mph
5th-50mph
