Hi all,

So flashed Tune+ yesterday and it's fantastic, but now I occasionally have a high pitched whistle around and above ~5.5-6k rpms. No loss of performance, boost is steady, everything appears fine... is this just intake noise that's decided to pop in with more power now? Haven't encountered anything like this before (limited experience with performance cars to begin with).

Any suggestions or input are appreciated.

Cheers

Anytime I've heard a high pitched whistle, it's been a loose FMIC hose about to pop loose.
