Those numbers are for WOT psi(vacuum gauge off). 43.5 is the technical value, but 41-47 are all within spec for the computer. With the line connected at idle the pressure will drop corresponding to the vacuum the cam pulls. Stock cams will drop the psi ~6-8psi, while larger aftermarket cams may only bring it down 3psi when you connect it.

More importantly is that the psi rises with rpm and load, and does not drop as you give it gas.

Should be fine.

Your going to have to adjust it a bit once you start driving, but once you get it set its mint.
