kinda stupid question but i still cant understand it. My 1988 VMAX doesnt have the vboost controller yet it does the servo noise on startup and i feel a pull when im in high rpms. What exactly does the controller do and is the vboost functional without it? HELP PLZ! (also the cylindrical plug for vboost looks like its coming out of my ecu and the 3 hole plug isnt plugged into anything)
Can vboost can still be operational without the controller??

Suggest you have a read of pages 7-59 to 63 of the Service Manual which explains the function of the V Boost system.
As far as I know, how the servo motor operates is determined by the controller therefore no controller = no servo motor operation.
Do you have the OE ignition unit installed?
Pictures of what you have would help.

Ignitech ignition doesn't require the controller . Perhaps you are hearing the fuel pump? The boost won't cycle w/o a controller when using the the stock ignition unit.
The controller gets vacuum and rpm data from the ignition and uses that to open/close vboost valves. It also "senses" the valve positioning.
