Right peeps
New intercooler fitted and there's a massive difference in the power of car much more responsive to the throttle....... but there is a "new noise" that I've noticed its a much more pronounced whistle hissing when you apply power I have narrowed it down to coming from the air filter box lid where the large pipe goes on .
Sound a little bit like dump vale noise but no dump valve fitted any help is this normal now that the intercooler is good ?
