Installing Manual Boost Controller

[kaidoy]

How would you install a manual boost controller to a stock sr20det. Specifically, this one: D.I.Y. Manual Boost Controller (http://www.geocities.com/chmwatson/FAQs/mbc.html). A writeup with pictures would be nice. Thanks in advance.

Umm.. that was a fairly comprehensive write-up.  What more could you want?
Except that install is fairly incorrect according to all the MBC's I've ever seen.  You don't splice in between the BOV and manifold, you splice between either:
A) The actuator and the turbo (internally wastegated turbos)
or
B) The line from your intake tubing to the wastegate.
All it is supposed to do is remove air from that line, which will mean it takes more air to push the spring.

Ok, so i have this hooked up the way the guy above says for a internally wastegated turbo.. Correct me if I'm wrong... I have a vacuum line from my throttle body to my BOV, and i have a vacuum line going from the wastegate to the bleeder side of the MBC, and a vacuum line going from the turbo nipple to the ball and spring side of the MBC, it allows me to pull extra boost, but when i go into boost, i just keep building it, it gets to 15lbs and let off before i overspool.... what is wrong with my setup...?
