Goulds jet pump not going over 30 psi

1. foot valve OK
2. new 30-50 pressure switch
3. 28 psi in pressure tank
4. New check valve and it's OK
5. Cleaned venturi nozzle. Problem still there.
pump runs and will only reach 30 psi. Turn off power and it holds at 30 psi. Use water and psi drops. Turn of power and pump rises to 30 psi and will not go further.

Any Ideas???

How old is the pump? Has it ever been able to achieve higher pressures?
