Sounds like u like dump valves way to much lol maybe they all have different spring rateings in them? they do all defo make different noises but do also sound chav lol i had a baily one on mine when i had 350 at 25psi that hissed and was just embarrassing now people say its not the valve that chatters anyway i put a spec r one on it as they look much better under the bonnet and it chattered lol still have it on there now with 500bhp at 2.6 bar and it chatters and flutters like f**k lol dose sound cool but again embarrassing in front of people who dont get it or know what it is
