25 psi at 2000 rpms is good, if it is not cool, check the high side, is it between 200-300? If it is much higher then you have a blockage in your system and I think you actually are an ounce too high on that charge. How long was it vaccumed? a half hour is minimum for a good vaccuum. I suggest 45 minutes. Also if there is alot of dirt in the condenser or the fan doesnt come on it will not blow cold, verify these as they are the easiest to test.
