I have a 2009 WRX that I recently bought. The dealer ship stated that I a brand new turbo put into my WRX. But, here is my problem:
I know what the normal squeel of the stock turbo sounds like. I hear it through first and second. But, when I get into third gear I only hear the engine rev'ing. And, once I get to nearly 4,000 rpms I hear a almost grinding squeel sound that makes me back off of third gear. When I go into fourth and 5th I don't hear it. It's only in third gear. I'm not to handy with cars so if someone could inform me if this is a potential issue with my turbo(or not) it would be greatly appreciated!
