Review on 1-30 PSI Universal Turbo Engine Controller Kit - Adjustable Boost Pressure Regulating Valve - Aluminum Control Valve for Car Turbo Engines by Hector Watkins

So I bought this with the intention of using it. Looks very nice, but not sticky at all. I removed the connectors and made sure the o-rings were in place, put teflon tape on the threads, all hoping it would work. I decided to try this with my MITyvac and luckily I did. It wouldn't hold a vacuum. I pumped it up and he fell immediately. It is not worth. Don't waste money.
