Thank you for the input on this.

I'm thinking that your readings are assuming the orifice has not been changed to a R134 orifice.?

I was advised on another thread that the original orifice should be changed when converting to R134. The size recommended was a #61 size.

Keep in mind that I'm NOT going to use the original A4 compressor but will be using a Sanden 508 along with a new evap, condenser, dryer & lines.....
