I agree 40psi is on the low side but in a 2 storey house depending on stud height, the pressure loss between floors would only be between 4-5psi. Therefore is the pressure the problem or the flow? Is the problem at ALL outlets upstairs? If the pressure is maintained at 35psi upstairs but drops considerably when a faucet is opened there may be some restriction in the pipework or faucet.
