this is not my first turbo golf with a k03 turbo but it is the first that ive tuned this far stage 2+
When i accelerate like any other turbo it spools and whistles as it should and is loud but i can hear what sounds like a bell. a ratling but higher pitched. Is this normal as to me im worried it may be the turbo internals. bearings maybe. any help is appreciated. also feels a litle down on power but nothing major and probably in my mind.

Common, have seen many 2.0 tfsi engines do this now, mine did it on the way home today, datalogging shows up no problems. Im going to try and reduce ignition advance and see if it goes away, this is all I can think of causing it but its unlikely but possibly worth a try.

oh i see well would appriciate it if you find whats causing it. Dont mind it making the noise as long as its doing no damage.
thanks
