DEM to Slope

I'm trying to create a slope map using a DEM file. I used the spatial analyst> surface> slope function. I wanted the map to be in percent slope/rise and not degrees. When I do this, the map it creates looks right, but the units are way off and the ranges for values are extremely high, all the way to 440? I tried to make sure that the DEM and the layer I was working both had the same coordinate system, but at this point I am lost and not sure what to do. My other question is that would it matter if I use 3D Analyst or Spatial Analyst, just out of curiosity?
