2 things wrong

first of all my car idles funny....but when i start to roll its fine...juss rough idling, it idles around 800rpm, and the other problem is...my turbo is too loud for stock...everythings stock...and the bov is loud too..it sounds cool but im pretty sure its not suppose to soun like that...somone help me :banghead:

year? engine? what knid of noise, does it sound like a bearing going bad or more like a air leak???? the idle problem could be related to your turbo pick one and fix it then the other might go away.
the first thing id check would be whether the turbo wheels spin freely or if they're seized
