No not really it sound pretty normal mate the only thing I can think is it's the wastegate penny on the turbo as it's not welded it has a bracket that's holding it shut and it's tight no movement. But since fitting the ewg the dump valve sounds different but is that just because I'm not hitting high boost as it's a greedy type s an it used to whistle now it gently dumps ?? I am going td04 or maybe tf035 in the next few months so I didn't fancy having to mess about striping it down
