Vaccum at Idle on boost Gauge
I searched around and couldn't find anything exactly like the issue I am having. This morning I noticed that at idle the boost guage was reading a 10 vaccum, which is much more than normal. While driving it will only spike to about 10psi. The MBC is set to peak at 25psi. I am thinking it has to be a boost leak but wanted to check with the experts before I start troubleshooting? Thanks for the help.

I am also experiencing my vacuum at idle is at a steady 10. I am new to the turbo world and don't know much, but as soon as I get back from the field I will check to see if I have any leaks. But I would like to hear any other possibilities on what it could be.

My MBC is set to 25psi and my vac at operating temp idle is 10 in/HG and spikes to like 15 in/HG while driving. If the vac isn't back to 10 in/HG or pretty close to it when I disengage the clutch the car stalls. Is this indicative of a boost leak or vac leak?
