I have a 2025 HO with 5200klms the engine had a rattle in it around 3600 revs and above from new and I suspect its wastegate rattle, however 300 klms ago the rattle disappeared and the acceleration on the throttle had changed.
When you pressed the throttle it would give little response until it hit around half way (which is not like the HO as it was very responsive) and the rattle is no longer.
