If Hi side more or less normal, but Lo side low, could be blockage at orifice? but you said you had a new one. So ... not sure. Best to look VCDS, compare between 44F and 90F (such as ambient air temp, pressure, etc).

A/C can be very complicated to diagnose. I am glad my issue was just hi-pressure sensor - still took me some time and work to finally narrow it down.
