Did you vacuum the system after you replaced said parts?So I'm in range on my low side, but the high side is really high with components being brand new, including orifice tube at condenser. The only thing not replaced is the Evaporator.

I think on the orifice tubes it depends on year where it is located. The later years is in the condenser and the early years is inline somewhere around the inner fender.And did you flush the evaporator? And you’re sure you don’t have two orifice tubes installed? (I think there’s two optional places on our trucks).
I was just going to say that about "fake" 134a.Really high pressures on the high side would suggest a blockage somewhere, poor air flow, or possibly way overcharged. Those pressure charts typically refer to operating with the fresh air door open. Also, watch out for R134a Replacements. It's not real R134A and operates at different pressures and temps.
Project Farm on Youtube has a video on it. He did what I say is a fair and mostly scientific comparison.I was just going to say that about "fake" 134a.
Great timing. I like his approach to testing. I'll try to check it out later.Project Farm on Youtube has a video on it. He did what I say is a fair and mostly scientific comparison.xc_hide_links_from_guests_guests_error_hide_media

On some trucks orfice tube is IN the evaporator (bottom tube to make it extra inconvenient)Yes, and then in certain years on the Suburbans with rear air (RPO C69) - Tahoes too IIRC - the front orifice tube was near the fender, after the wye where the HP pipe splits to feed the rear.
In the rear there's a TXV mounted on the evaporator; no orifice tube in that circuit.
