I've just heard a new noise when lifting off full throttle - sounds like "shhuck" - very short noise and doesn't happen when decelerating from half throttle - not sure what is making it - anyone else had anything similar?

Shuck! Kinda hard to tell how shuck sounds lol. Pigeon/owl kinda noise? Could be wastegate?

If not engine mount or something allow big engine rock?

I will not be the wastegate as the vRS doesn't have one. It uses variable intake vanes to control boost. Diesels don't have Dump valves either.
