pcoupl = yes doesn't do anything.  You have to specify the type of pressure 
coupling (grompp should tell you that).  For a discussion of the differences of 
NVT and NPT (and statistical ensembles in general), do some background reading 
on statistical mechanics and thermodynamics.  It is hard to say ad hoc whether 
or not NPT conditions will change your data.
