Low Vac at idle

[adidasdudegst]

havent thoroughly checked cam timing yet, but the marks line up dead on. Also, dsmlink reads 20-25 at idle, where the boost gauge reads 11 in vac. Is dsmlinks boost source reliable? I cant remember where it gets the data from

2g's have a map sensor on top of the intake manifold.

So is the MAP sensor (dsmlinks vacuum/boost readout) just as reliable of a source for boost and vac as the boost gauge?

No

I have the FP intake pipe with BOV return, so i just routed the charcoal canister hose down behind the firewall, would that cause loss of vacuum? I would think not considering it is blowing out fumes, but im not 100% sure, so i figured id ask.
