I have been using GT's PRISM injector which utilizes dry vacuum. It sounds like there may be a misconception regarding this type of injector! You can't remove moisture during the dry vacuum cycle, unless you heat the interior glass while in the vacuum cycle. But, where will that moisture go? I still use a moisture evaporator or mini torch prior to placing injector over break. I don't believe dry vacuum injectors were made to eliminate moisture.
