Dump valve

I read some comments about the dump valve, everyone spoke in positive aspects, but nobody wrote anything negative. Is there any harm to the engine? It also says that it means the same as blow off valve. is it true? I want to get my car installed but I don't want to have a lot of chug sound like blow off. If there will be a lot of sound, I will give up Meanwhile, the vehicle was 208 gti. Good forums.

I have no idea. I do not think there will be any ideas here, they can be found in the modified forums. The healthiest answers of these are you can only get information on the sensation.

I already wrote that there is someone who knows or hears, thank you
