45 on the low side and 240 on the high side at about 80°

25-45 is the normal low side pressures, which is what you will mainly use for filling per pressure. 25 would be on a cool dry day, and 45 would likely be a very hot and humid day. You can find charts for temperature/pressure.

I looked on google and I couldn't find it.. I live in Michigan during the summer it's very humid..

crazy guy do you have A/C equipment? vac pump, etc?
I installed a new condenser but need to do a leak down test.
Maybe ill load in some dye and pressurize it, the dye will look like a murder scene under black light if there's a leak,
