Looks like 36psi with the vacuum line applied which is normal. And when you turned the car off you actually got 43.5 whichis the reading without vacuum. Buy a Holley adjustable regulator and with the line disconnected adjust to about 48 to 50 psi for a little more power.

I recommend this Holley unit. It the best one out there. The BBK unit is really chessy.
