Is your slicer set to auto-scale objects to fit the bed?

You should be able to see in your slicer the size of objects. Do they look right there?

I don't know about the scaling problem, but why are you using an ancient version of slic3r? Get the latest developer version 1.3.0-dev. It fixes many bugs in even the latest stable release (1.2.9).

could it be your calling slicer from another program like pronterface? and not running it manualy?

There used to be an issue if you set up slicer wrong, proterface would call slicer, it would fail but the original gcode file was still there... so pronterface got the orriginal gcode, every time.

try a completely different object, say a cylinder, verify it really is looking at the new file as I suspect its not a scaling issue
