Hi guys, I have a deep whistle during acceleration, i can also hear it with the window down when not accelerating, just cruising. It sounds like it's coming from the top of the vehicle, the left side. Could this just be wind noise, please see the attached video, any help would be greatly appreciated! New to stageas, and new to turbo vehicles. I have a 2001 Stagea 250t rsFour Thanks in advance! http://cloud.tapatalk.com/s/59932df212a26/20170810_9565.mp4
