Tail width - wider tails tend to stay flatter; narrower tails are easier to put on a rail. Consider bumps or wings to pull in the width and create a "pivot point" (really a "release point").
Fin placement - clustering the fins closer together, or pushing the cluster forward can help loosen it up. So depending on your fin system, you might want to try that first, if there's any adjustability options.
Fin size - smaller fins will give you more slide, and let you push the tail around easier and tighten up your turns.
Tail rocker - a bit of extra kick in the tail will help cutbacks and snaps
Rail line - shorter rail lines, like diamond tails or battails with a longer center point, will also tighten up your turning radius. Fish tails lengthen the effective rail line.
Bottom contours - adding vee out the back, or even going concave to flat behind the trailing fin adds some rail rocker and release out the back. Also... if your current board has a single to double concave, omitting the double might make the board less drivey and more responsive.
All of these options come with costs, but have their advantages.
