The manual auto-set wedge only has two positions, stowed and deployed.  When deployed into the "floating" or down position it has a slight range of movement determined by the optimal maximum drag, but the position is not adjustable. 

The power wedge has an auto feature that lowers and raises the wedge automatically from the down "lift" position to the selected drag position at different speeds when using the cruise speed control.

Hello there, I’ve got a 06 21’ vlx with the auto set wedge and I’ve noticed no matter what speed when surfing or pulling a wake boarder it stays all the way down and doesn’t seem to be setting itself in the water. Just curious if that’s normal or I’ve done something wrong in installation

Could be a problem with the neutral safety switch in the shift controller.

The screws hold the dash in place, so they are necessary. Probably not enough room for the screw heads to fit smoothly under the sticker decal.
