vacuum and pressure are inverse... so when vacuum is up pressure is down, and when vacuum is dowm pressure is up... like with fuel pressure, vacuum is up and pressure is down at idle... so when you start to accelerate vacuum is going down and pressure is increasing...

Just play with it. If it's the wrong way you will definitely notice something wrong in your powerband. I ziptied that actuator arm the wrong way (up/down??) and I thought the motor went kapoot..! ..had power up to 2k rpm lol, engine would scream and go nowhere..
