Gfb bov

[Eli1k]

So I purchased a gfb blow off after installing everytime I let off gas and the bov goes off a split second later I hear a little clunk idk if that’s the bov shutting after or if it’s defective

I assume it was installed properly with the stock hoses. Double check the spring make sure its not too loose or tight. I normally leave it near stock level the way it came but just slightly looser. My gfb 9012 never makes a clunk sound. Might need to reach out to gfb. They are fairly quick to respond.
