HKS evc readings?

[ste-glanza]

Right so i have a hks evc fitted, when the car is ticking over it reads -52kilopascals on the screen, is this normal or does it mean i have a boost leak? Should it be at zero?

cheers lads

Thats normal that its in the minuses not sure though think mine goes down to like -36 or something
