Compressor is running all the time - windows open, blowers on high. Both readings are the low-side. Only difference is whether the radiator fan is running or not. Now why on earth should this make a 15 psi+ difference in low-side pressure?
I tend to agree with you, that it needs a LOT more refrigerant - uisng your numbers it only has 300 grams or so, less than half what Saab says. But it also seems logical that the correct reading should be the one obtained when the radiator fan isn't running, and that is 35 psi, which is as high as it should be. Very mysterious.
