Holds boost but low Vac

My car recently is only displaying 10 inhg. Car runs good at idle. Dont have a vag cable yet to check. I assume i have a vacuum leak. Im not sure where\ and how(other then looking at line) to check for a leak.

did you make sure your boost hose isnt kinked or loose? vacuum isnt measured in psi or bar on most gauges. i think mines around 20inhg at idle tho so his isnt sucking as much as it should
