Instaed of just using setData(), use Level.setTile(x, y, z, Level.getTile(x, y, z), Level.getData(x, y, z) - theDataYouWantToSubtract).

And that setData doesn't seem to set a tile's damage value, it sets the item that the player is holding's damage value.

And the -3 method wouldn't work as that would be setting the tile's damage value to -3. And a tile's damage value cannot go lower than 0.
