Strange noise under heavy acceleration

Asps91 · 01-10-2015, 02:55 AM

Hi guys,

I have just bumped up my tune on my cobb to stage 2+ fmic aggressive (I have all the supporting mods and fuel) and have noticed a strage noise under heavy acceleration when boost is building.

The sound is comparable to when the windscreen wipers are on and there's not enough water to lubricate the rubber and it squeals. Hard to explain :confused

Has anyone had this before?

Where is the sound coming from? Does it happen only during spoolup, or right when max boost hits?

Seems to be when max boost hits
