I've heard of people making there own, and I think one thing used was a part from an air compressor? A pressure regulator or something? I figured I'd look into that since it's supposed to work fine and cost much less than aftermarket MBC's. Anyone got any info?
You need to change out the spring though. The internal spring is very thick and strong! It is not precise with that spring. Home depot sell a box of misc springs and thats how i changed out mine. With a lighter spring you can turn it about 2 turns for a pound of boost.
