The size of your texture will be different depending on the mesh size. To change the size of your texture press M on the selected object again. When the materials window pops up again: 1 press the green button to bring up the edit texture window. 2 grab in the center of the 6 way cross object and all three scales X, Y, and Z will change at the same time. A good place to start this texture is around -5 for each of these. If the spiral is too steep you can change the Y individually. Unfortunately you will just have to play to get this to work for you.
