Are you sure you are using exactly the same macros?
From svn the major differences are in the GEM geometry and digitization, which could introduce a lower efficiency in the gem region (up to 20%).
In your monodimensional plots I do not see a large reduction of efficiency between protons and antiprotons. And nothing in particular after 20°. Or at least I cannot judge that something is going wrong.
