*edit* The title should have read "Can I use the pcv valve vacuum for my boost gauge?"

Right now the BOV is T'd into the fuel pressure reg. vacuum line. The turbo compressor doesn't have a fitting so the wastegate is T'd into the brake booster vacuum line. Since the fuel pressure reg. vacuum line is already T'd and the brake booster is also already T'd, can I "T" off the pcv valve vacuum line for the boost gauge and will it give an accurate read? Thanks.

It should work as long as you tee before the PCV valve itself since it's a check valve. The boost gauge vac line might also get some oil from crankcase vapors in it since you're teeing off the PCV line, and that might affect how it reads over time. Your best solution would be to get a vacuum manifold and tee it into the brake booster line and run your lines from there. Some people frown upon teeing the FPR line since it might cause your fuel pressure to fluctuate which could lead to problems if you run lean.
