I am servicing an AC for a 01 Pontiac Grand Am. I need to know the High and Low pressures (PSI) for the 134a. I have a service manifold with gauges. I know the Low should be around 45 PSI but the High side still unknown to me. Searched everywhere with not definite numbers. Came across with 190 to 210 PSI, is that true?

Thanks in advance.
