Well if it is acurate, then my damn MBC wont tune my boost. I'll run 13/15 all day. No matter if that thing is all the way in or out. Does anyone know, on a 2g, if the line you tap for a boost gauge has blue lines on it or not?

Boost leak? Or just the weak T25. Does it at least spike past 15 to start? The T25 will only hold like 13-15psi in the high RPMs.
If your gauge reads vacuum on intial startup then your probably on the right line. Even if your on the wrong line, if your getting a boost reading then it should be accurate if there is no leaks.
Tapping of the BOV or comp housing or comp elbow should have no effect on spoolup time. Think about how it works...
Tapping of the BOV line should give somewhat more consistant boost levels from one day to the next because it takes into effect how well or not so good the intercooler is doing it's job. Getting it pre-intercooler pretty much makes the turbo always run the same boost, but you could end up with varying boost levels at the intake manifold/motor depending on how heatsoaked the intercooler is because the better an intercooler is doing at it's job of cooling the more pressure drop you will get post-intercooler.
If you are trying to run as little boost as possible, then tap it pre-intercooler. Then the wastegate will get to see the most amount of boost pressure the quickest and be able to open sooner.
