Timeing & Vac. Advance Question.

I have a 1988-9000t. I know that the timeing advances with vacuum and as the vacuum decreases the timeing retards. How does turbo pressure thru the vacuum line affect the timeing. There is no check valve on my car. Does turbo pressure go into the vacuum line? How should I set up the timeing and vacuum for best performance? I hate to sound so confused about such a basic principle but vacuum is caused from the piston pulling air into the cylinder. At higher speeds should the vacuum be greater. When does the vacuum turn to pressure? Thanks-Ron
