And then you do debugging. Adjust the screw at the top until the car's idle speed is stable!Turbine pressure regulating valve: Pressure regulating valve, regulating air pressure, improving engine performance, reducing fuel consumption When the turbine is in action, the internal will produce extremely high pressure. Although the turbine itself has an aperture to release high-pressure gas, it is still insufficient in the face of continuous pressurization. The pressure relief valve can quickly release high-pressure gas to facilitate the next pressurization operation. In this way, not only the turbine can be protected, but also some turbine hysteresis can be eliminatedPackage List:1 Turbo Engine Boost Controller 1 set Installation AccessoriesNote:1.

Works great !!!!!
Comes with different springs for boost levels. Spring that was in it gave me 20psi at max adjustment so swap spring if going over 20psi like I had to. Once spring swapped achieving target level was a breeze. I am impressed at this price point.

Works well
I only used it for one race night because my wastegates got delayed and it got the job done well

Needs a softer spring
I had to cut down the spring to get full range control for testing. It needs a softer shorter spring for very low boost applications

Seems decent but could use improvement.
For the price, I can complain. It’s a simple manual boost controller instal, but wish it had little dashes to tell you how much each turned equaled in terms of boost pressure. Besides that, I’m pleased!

One rotation=1lb! Well made and works great!
Knob spins smoothly, didn’t have to take it apart and debur. Works really well out of the box! 10lb spring in wastegate and spring that came in controller equaled one pound of boost per rotation. Only thing I wish it had was a detent to make it easier to count rotations.

Boost controller is garbage out of the box.
Waste of my time boost controller comes with extra springs but so weak they will never do the job. Pressure check it and it leaks, Ad another spring and it leaks .will it pop off at pressure....NO it always leaks It is worth nothing. I wish I could give it zero stars...
