thats good to know. the noise reminds me of bad car films, spotty chavs in sportsgear with bad haircuts and sterling silver 25kg necklace/bracelets. i find them most pikey. having said that, i used to 'dig' them but as i approach thirty the fact that 15yr olds look around knowingly, and 30 year olds look around with a sneer makes me reavaluate what i dig. if they dump at full bost or therabouts then there ok. its when they dump at about 2psi they get on wick. how do you alter the boost at which they operate at? is it possible by altering the spring rate? assuming its a dv26 of course.
