    Hi i have a 2002 s3 bam engine with a mtm remap and hyperboost diverter valve i have just done the wak box mod and noticed on light throotle you get a little whoosh sound i know this is normal. But under hard acceleration change gear at around 5.5k revs i get quite a loud dump almost like a vta dump valve this isn't normal is it?.
    Thanks

    Yup that's normal mate. It's like having an induction kit which sucks in alot more air. Was it easy to do the Wak Box mod?
