Ruddi444 Posted October 13, 2015 Share Posted October 13, 2015 Noticed a weird noise happening, when I release the blitz dump valve normally or heavily on boost sounds normal, but if I slowly release it , or release it out gently it begins to chatter or shudder first? And something sounds not right like air escaping or something? But I have checked all hoses! Recently fitted a hks mushroom and its a standard glanza so any ideas or shed some light? Much appreciated Quote Link to post Share on other sites
asbo-v Posted October 13, 2015 Share Posted October 13, 2015 Might need adjusting via top lose spring As some are adjustable. Quote Link to post Share on other sites
5T4R7ET N/A Posted October 14, 2015 Share Posted October 14, 2015 ^^ as above, it might be a bit too tight for lower boost hence the chatterOr the bov is sticking and it needs a good clean. Quote Link to post Share on other sites
