Hi there Ive just fitted a new CAI kit to my octy vrs, took it a run and didnt hear any induction noise at all. what I did hear was a loud hissing sound. Its when on the power and boosting. rolled window down and was really loud, people looking etc. Car seems to run fine etc. is this normal ? or do I have a leaky turbo pipe or something. Another question ! if I was wanting to check the boost pressure where would I connect a gauge to?

Thanks

Bob

Nop, nothing wrong with the car. That's exacly how K03's sound when sucking air. Induction noise IS a loud hissing. Where is your CAI routed to?
