A/C Hi & Lo Pressure Readings

A/C Hi & Lo Pressure Readings
Ok, I have searched the best way I know how and, surprisingly, am still coming up short. Thus, the question:
Anyone have the factory service manual instructions/specifications for checking the high pressure and low pressure sides of a 2005 GX470 air conditioner?
What I am used to is test conditions (e.g., AC on manual high, fresh air mode, coldest setting, 1500 rpm) and then an ambient temperature range, low pressure reading, high pressure reading.
I can find lots of "generic" R-134 charts that are probably "ok", but if anyone had the FSM excerpt, that would be useful. Otherwise, I'll have to buy the 2 day subscription....
Thanks for the help.

Ahhhh, ok, it's a function of the refrigerant, not the vehicle. Makes sense. Explains why I can't find a chart anywhere for a Lexus GX.
It was 95 degF outside, high humidity, and I was at 300 psig. Low side was 50 something, IIRC. Looks good to me.
Thanks for the info!
