Hay Ya'll, it's been a while. The Revcon still lingers (don't ask) but todays challenge is about Duracool in a 2003 Dodge RAM. I overhauled the AC system and I was short a can of 134 so i topped it off with Duracool. It was amazingly cold. Unfortunately, it leaked down and i had to go back into it. Now i want to use all duracool.
It's cooling the truck OK but the line to the evaporator is frosty. Pressure is about 24 PSI with the truck idling at 700 RPMs. I have been told that with Duracool a high vacuum like 27 inHg is too much and it should be something like 10-12 inHg
So what pressure should i be shooting for and should i purge it and vacuum it down again to a lesser vacuum?
Thanks

It's gonna take a lot of Adderall to get this thing right.
