Review on Universal Aluminum Manual Boost Controller: Efficient 30 PSI Closed-Loop Control Valve for Car Modification by Prince Burr

I've taken several inexpensive MBCs, this one was actually the cheapest - and I had low expectations, but this one lived up to it! Unfortunately, the other two didn't work properly. I put this on the car and got the boost where I wanted in about 2 minutes (which was admittedly a bit of a godsend regarding my initial setup). It's just a regular ball spring valve, which obviously doesn't mean anything. new, but why screw up something that works?
