selling a used Forge BPV $50 only issue I had was it was getting stuck and not allowing the car to build boost, when it dropped below 35 degrees . It hits boost a lot faster than the stock BPV...and also makes a ching sound when you let off the throttle (kinda like 2 swords hitting each other) ..I also should have the green spring somewhere as well ...but comes with the red, blue, and yellow spring and spacers.
