its cool to fabricate your own shit but when it comes to controlling boost, i personally woudnt mess around. not to mention they are so damn cheap. y build your own?

all ya need is some $$$ and buy one....

I made it, and it works just as good if not better then my $80 Turbo-X's boost controller. But this is just my oppion, based on how i thought it worked.

The only thing you have to remember is not to get to stiff of a spring, if your spring is too stiff your going to be hitting 18psi at the lowest setting.

And if you don't have a after market boost gauge i suggest that you get one, before you install this.

there are tons out there for 50 bucks( sbr, joe p, etc.) . very sick awd n it, that you were able to build your own boost controller with no problems. dont even think about turning the boost up with out a real gauge.
