IFDG

Hi,
I have downloaded loads of ifdg a319/20/21s. Firstly, i think the aircraft are excellent (i mean the textures!).
However, my aircraft don't fly 'to my taste', in comparison with other boeing aircraft. Is it just me or are a320s supposed to climb at say 2000fpm with an airspeed of about 180 because that is what happens to me.
Is it possible to alter some figures in the aircraft.cfg because i would love to fly these aircraft regulary but the performance lets them down.
Is it the way i fly them or is it a general problem?
Many thanks,
Richard.
