Following as I have pretty much the same readings on my truck. All new hoses, POA adjusted for 27.5 new dryer (that is labeled R134 and has a sight glass). It does seem to be cooling fairly well especially at hwy speeds. In my research it does seem that the values listed for R134 don't seem to match up with R12 system conversions.
