Audi A3 2.0T Odd Air Intake Sound

Hi i just installed a K&N Air Intake for my 2006 Audi A3 2.0T Quattro.

Picture after installation: http://i42.tinypic.com/2yopqwj.jpg

I had already mapped my car to 242bhp, and have a Remus Power Sound exhaust installed.

Today after the install of the Air Intake my engine makes a strange sound at 4k RPM. Above it its fine, below it its fine. You can hear the sound on the youtube video.

I can not find any leaks in the pipes or connections.

Any idea what this might be? The car drives fine, and performs well as far as I can tell.

Thank you for your time.

Turbo spooling up and blowing past the dump valve,fit a modified dump valve to cope with your alterations

On monday im taking my car for a 60.000km service. do you think audi can sell me one of these valves? or do i need to go to a tuning shop for this?

I would look at a modified valve to cope with the mods,there is a kit for the 2.0 tfsi but unsure of the 1.8 tfsi

I can't bring my car to a shop before thursday. do you think driving it can brake the car/make it worse? as i need my car everyday... and its only sunday atm.

should be fine but try not to get to excited with the rpm until its checked over to locate possible leak under boost or weak dv
