Does anyone else with veccy c + k+n panel filter have a turbo whistle when driving. Its hard to explain the sound but if driving around 2.5k-3k with foot resting on the peddle it sounds like the whistle on a kettle.
Messing about with the car today I could hear the same noise over the top of the engine when i was at 5k+
Is this a normal sound with those mods, sure i never noticed it before i did them, dump valve also seems to be fairly audible, which it wasn't when i first got the car. Have got a VXR turbo but running standard map.
