Low side pressure for 410a.
With 75 indoor you should be running approximately 190 on the low side. The correct way to charge the unit would have been to weigh the charge in and in the cooling mode. So if you have 190 suction I would leave it as is and return when it is warm (70) outside to adjust the charge. Experience: 35 years in HVAC.
