Added a digital boost gauge onto my 84 GSL-SE to measure the pressure going to the 5th and 6th port actuators. I have seen it go up to around 3.3 PSI. It is interesting to see at what stage the ports are opening.
that is a great way to have real time data. I assume it reads vacuum as well, so it can be used as a "fuel miser" gauge to help with economy during long trips.
quick tip for checking actuator function. I used a bread tie clip. Placed it on the actuator rod at the base of the shaft. When the rod trained through its motion the bread clip was pushed up the rod.
Yes it did Richard, I have also had success putting bearing grease on the actuator rods and after driving observed the portion of the actuator rods without grease on them.

did this make sense to anyone?
That's a good idea, I will also try that. I also need new gaskets as I am running them without at the moment. One of the actuator arms was actually seized. I pulled the actuator off and lubed it up and it's working again. The guy that used to drive it never drove hard enough to open the ports.
