Drivetrain Stock boost PSI

Yeah, almost without a doubt. I would start by installing the BPV. If yours isnt functioning right, it may cause a failure in building boost. If that doesn't do the trick (but I'd bet money it does), check the vacuum lines where you spliced in the boost gauge then the rest of the vac system because you're apparently hemorrhaging boost somewhere.

and for what its worth...EVERY forced induction car should have a real boost gauge installed. its very useful and really helps you troubleshoot.

My ipod touch reading Tommy's boost using REV. for the iphone/touch via the OBD-II with a PLX wifi link. I had it data logging boost for his power run.
Basically a set of WOT runs in about a 1/3 - 1/2 of a mile.
Rev. is only reporting what is coming off the OBD. If you folks think with his mods he should be getting more, then he has a leak or other problem.
But it sure felt good on the butt-dyno.

Just read the earlier posts and you'll find your answer as far as what could be wrong, I actually had a small kink in my line giving me a low reading. As far as the BPV issue, 90% of the time this will be the cause if it's still the factory unit ( esp. in pre '05 cars) it usually has to do with butterfly alignment. For the cost of one of the DT/BPV's you might as well just just start there and take it out of the picture.

Just bumping this old thread because it is forever relevant AND I just replaced my turbo (worn housing where the wastegate actuator goes through) and most of the piping (removed noisemaker and resonator) at 125,500mi on my '08 S Clubman. Using my bluetooth ODB reader, I'm getting 35-37 inHg at full boost which equates to just over 17psi. I did NOT upgrade my turbo. Just replaced it with a like sized K03, but I DID replace my wastegate actuator vacuum line with a silicone one as well.
