To see vacuum you need to be after the throttle plate.
Also tapping into the intake after the throttle plate sees what the engine sees with regards boost level. Tapping before the throttle plate should read higher because of the pressure drop across the throttle plate which I guess may be as high as 1psi or so.
Anyone know this value at 1 bar boost from the turbo?
