Hi I'm new here. Picked up a brand new Nitro Xr6 Turbo 2 weeks ago. Now has 1200km on it. Got premium sound, leather, tech pack, alloy spare, mats, mud spats, tint etc. Absolutely love it. Having never owned a turbo before, I'm not sure how it should sound. There is a slight whistle/whine from the turbo when you accelerate normally. Doesn't have to be full throttle, just normal acceleration. is it normal to hear the turbo? You can't hear it with the radio at normal volume. Only when the radio is off. Thanks.
