Review on 🔧 GrimmSpeed 070002 Boost Controller - Enhanced Black - Manual Control for Ultimate Performance by Noel Pilla

The sun is making it difficult to see anything in this image. But the white lines and numbers above quickly disappeared after testing my product. Rotate the handle all the way down and then up. after that once before you even put it on the car. He disappeared. I just hope it doesn't go away entirely. The dual ball bearings work, but they quickly reduced the click noise by just 8psi after running. But it's still a great product, feels solid and holds momentum well. No leaks
