F53 AC high side pressure (2008 - 134a) at 90F
Can't find it in any of my manuals. websites suggest 250 psi but wondered if that's correct. Other sites say 134a is very sensitive to the right pressure.

Normal low side pressure is 40-45 the night side will very based on temp how clean the child is etc. if you are charging it do it based on suction pressure.
