Does anyone know how the timing is retarded on boost?

was driving around with a vacuum guage t'ed into each side of the vacuum line to the dizzy to see how both the advance and the retard behave in different conditions. what I learned is that under boost both the advance and the retard produce pressure instead of vacuum, my 87 distributor only responds to vacuum, so how the hell is this distributor made to retard if blowing in the lines does nothing. I'm afraid I am driving around unprotected against detonation.
please anyone.
