The low side pressure is fine. The big unknown is what is the high side pressure.
Having 32 on the low side means nothing if the high side is 120. How cold it gets depends upon the pressure drop and that is dependent upon the expansion valve or orifice tubes on cars equipped with the latter. High side needs to be over 200 at idle.
A note here involving safety. If you decide to use a set of manifold gauges and have an open can of refrigerant tapped NEVER under any circumstances open the valve on the gauge’s high side. That would apply high pressure to the can and likely lead to a can explosion. Other than scaring one to death it can also be very dangerous. A second or two of refrigerant into the eyes can lead to your being blind. Forever.
