Emmm tryin to think mate if u want over the weekend ill pop down with my mate im only in baillieston
you might of broke the dump valve my brother done that on his subaru a few years ago only running a bar of boost swap one over and see hopefully thats all it is
ok my amazing linguistic skills have narrowed it down to a quick 'w-aww' sound
that would be great, but im going to be away for the weekend, is there any chance you are free tomorrow night, i could come to you?
ill try swapping the dump valve. It seems to be operating fine though, as i can hear it at the same time as the strange noise
no, its only when i boost hard and lift off
