Outside Temp: 74

Just wanted to know if these numbers sound right. It seems to me that the head pressure is to high (205)for 74 degree temp. but when I lower it to 165 to 175 my low pressure goes up to around 65. I have a ext. mounted trans cooler mounted in front of the condencer. Should I remove it to get better cooling. I don't seem to get but mid 50's out of the vents. I left the high pressure at 205 and wanted to know if I should adjusted the low pressure switch sence it was converted to 134a. Any advice would be a big help!!!
