What's your cyclic rotation rate? A very fast elevator carries a ton of inertia. Hard to stop.
Also don't be afraid to peg the needle on d gain. I have seen some need it that high depending on flight style and setup. Sent from my SM-N900V using Tapatalk

+1 mine's pretty high on both an N7 and E5-S due to the 360* rates on cyclic. The tail hanging off the rear acts like a large lever arm in flight. This is the same for a tail spinning at 720*
A low P gain could potentially cause issues as well. If a system reacts slowly to displacement from the setpoint (command to stop while moving), yet knows the set point has been passed and has a strong integral component (high I), it will attempt to go back. You can actually see this really well on something like a 130x, where if you lower head gains to deal with wobble, it can actually get much worse.
