Vacuum at idle

Vacuum at idle
As the title says, I wired up my boost gauge today and connected all the hoses. I'm using one of the nipples the secondary air injection used to attach to (very back of the intake manifold, should be a good reference point.) Started the car on the stock ecu, and vacuum is around -13ish. The gauge does move when I rev, so I'm assuming all is well. I just seem to remember my old GST sitting around -18 or -20 on my boost gauge. I'm guessing the F20 just builds more pressure at idle than the 4G63
