Unusual noise after installing ITG Maxogen + revision d valve

[steelandy]

Hi all,

i have recently installed the itg maxogen and revision d diverter valve on my K03 gti. in general car sounds great and i love it, however under acceleration at around 3k rpm i am hearing a strange deep whistle/whine.

Can hear turbo at about 2k then 3-4k or so this whine takes over and is louder than any other induction or turbo noise coming from the engine.

Can is performing fine and not loosing boost.

any ideas?
