Here's a couple of tables that you may find helpful.  One is the ICAO Standard Atmosphere Chart and the other is a table I built from it and a couple of formulas I dug out of the internet.  The 4.3 psi differential column is for a Twin Cessna I had for awhile.  I don't have a 5.5 psi differential column, but you should be able to create one yourself.

Notice that at 25,000 ft. MSL with a 5.0 psi differential the cabin is at 8757 ft. MSL (ignoring the temperature correction error.)
