Hi Guys,

Hoping someone can shed some light on this issue I’ve got, when accelerating and just before or around the car is about to change gear I hear a whoosh sound, no restricted performance, smoke tested and doesn’t appear to be any leaks, new intercooler. I’ve uploaded a video, sound is noticeable at around 9 seconds it’s like a snorkel sound.

I think it’s also rather more noticeable when it’s not, it’s been like this for probably 5-7k miles now and have been towing and no warnings. Any ideas would be appreciated.

Thanks,

Callum
