AC Low Side Pressure Question
At about 98k on the box and kinda felt it wasnt blowing quite as cold as it used too. I bought one of the kits with a gauge and it was a little quirky so I ended up with too much 134A in. That was obvious as the clutch will kick in and then kick back out and it doesn't cool well. I fixed that quickly and looking at this chart

I am right at about 50psi at 95 degrees when the compressor turns on. I do notice after it idles for a good 10-15 mins or so and the car gets colder it does drop to around 35psi. When it is not engaged the pressure is between 90 and 100, which I have read is right. Just idling in a 95-100 degree garage it gets to about 45 degrees, running down the road the cold air inside is 40 degrees at the vent in 100 degree outside temps. Seems to be working well and I think it is cooling better.
Anyone see anything different from what I am taking away from the chart and results?
