I am no AC expert, but those numbers suggest low gas, not stopped up capillary tubes. Stopped up tubes in my opinion would give you numbers such as 0 to 20 on the low side and above 300 on the high side. Airplane guy has the notebook for my old 390 where I recorded operating pressures for the Dometic system. To the best of my memory they were in the range of 60 on the low and 250 on the high at 90 degrees ambient, but don't take those numbers to the bank.
