Make your own boost controller!
My friend found this site on how to make a manual boost controller. Heres the site http://www.geocities.com/chmwatson/FAQs/mbc.html
Tell me what you guys think.

This one is going to show up in the i-Club Yearbook under the heading:
Most Likely to Blow Your Engine to Tiny Pieces and Shame You In Front Of Your Friends
I mean c'mon, I am as cheap as the next guy, but price the cost of replacing a turbocharger ($800+labor) or an entire engine ($8,000) vs the cost of a real MBC ($150) or even a SAFE Cobb Reflash ($400). Penny wise, POUND FOOLISH as my father loves to say. A manual boost controller is a dumb idea even if it comes from a reputable manufacturer; Subaru spent many years developing and testing that ECU module in your passenger side footwell for a reason.

Don't get me wrong, I love homegrown solutions! My friends and I have built some pretty crazy stuff from scratch (including turning a 10-speed bike into a trebuchet -- LONG STORY)...
...but the MBC, well, I speak from secondhand experience I watched a friend destroy his nice new Dodge SRT-4 in about three months by running 22psi in 2nd gear with an off-the-shelf manual boost controller. Watching that think smoke the front wheels (FORGET trying to turn left if you were on the gas :torque steer: ) was amazing, but ultimately costly.

um lol, you know running it at levels that high is just stupid, the idea behind a mbc is to boost w/o blowing up your engine.....which might require not trying to double your boost levels.
the idea behing that btw, is completely sound, you just have to not use cheap parts.
for those who cannot afford to reflash an ecu or get chipped, this is actually a sound idea. There are many variants of this around, this one is a bleeder, so it will not be as good as the other ballbearing/gvalve ones (more lag). if you safelybuild one that will hold, thats all that matters. people have been running mbc's for quite some time now w/o problems. the problems come from boosting over 2psi and such or from asses who buy a mbc w/o having a boostgauge.
if you compare say a gfb mbc or many others, you will notice that they are all the same thing really. Most are either a ballbearing design/gvalvish/bleeder w/ ballbearing. it looks cheap, but then again, the instructions dont require to mold your own piping into a "more professional looking" shape and doesnt require painting.
i think even scoobymods has a install on the graingervalve version of the DIY MBC.
