Vibrant Performance 16901 Boost Controller Kit

I typically use a less expensive industrial pneumatic regulator, but this looks nicer and is more compact to I decided to give it a try. This is not a proper pneumatic pressure regulator... this is just a little block which has a hole in the side that vents pressurized air and can be adjusted by a needle that blocks the self inflicted boost leak. That is not how a proper pressure regulator works and is a very low quality way to make something called a "boost controller". Would not purchase again, and I probably will replace it in the near future.
