I got myself a Astra Vxr- 2013 last week.
I need to ask you about what i think is a problem.
I got this noise, like a dump valve or something similar when i let of the throttle, the car has no mods.
It's only when i go over 2k 2,5k rpms( and higher) and let go of the throttle(prolly when the turbo kick in?). There's no such noise when the car i still and i rev it in neutral.
Hope you get what i ment!
Is it a problem or is it normal?
Sorry for asking but i have no experience about the vxr yet!
Thanks for any help i could get!
