What are the pressures on the high and low side when the car is idling with AC on recirculating and fan on high? Again, with AC running, what is temp in driver's side vent? What is ambient temperature?
Since the ambient temp was lower then specified above, the pressures should be even lower. When you charged it, did you first evacuate the system and then added refrigerant by mass or did you just add refrigerant until the system felt cool? I hope you charged by mass. So I would first slowly remove some refrigerant and see if that helps. Please capture the refrigerant properly or let a professional do it. It is illegal in the US (and most countries) to vent AC refrigerant to the air.
The system is designed to work with a certain amount of refrigerant...too much and performance suffers. Since you had to charge the system, did you check for leaks? A good way to do this is to evacuate the system, add some UV dye, and then charge with the correct amount of refrigerant. If it leaks out again use a black light to look for the leak. For larger leaks, a freon detector might work but I prefer using dye. It makes no sense to charge a leaking system without a repair.
