Nah no dash cam. There's a speed limiter?! Haha didn't even know.
Yeah I thought potentially it could be a whistling sound from a pipe as I recently installed an induction kit. I've checked all piping and seems tight. Is there an easy way to test for leaks?
I'm also suffering from quite bad rev hanging as well. It could all be related. I may just revert back to stock airbox at this rate.
