Review on 🚀 Qiilu Universal Adjustable Manual Turbo Boost Controller Kit with Bilateral Valve and Mounting Bracket - Enhanced Performance for Turbocharged Engines by Jodi Tisdale

Bought for my son's car. it works as it should. When it turned all the way it got 5 psi. I scaled it up a bit more where it's 15psi and it holds up well there. Make sure you've connected it properly. A simple search for a diagram will help. I didn't know what I was doing and I hooked it up wrong at first and it obviously wasn't working, thinking the controller was defective. After setting it up properly, I sent my son to test it again with the boost off. He barely made it to the street, came back and told me to give him his support back. In that moment I realized that it works!
