So I got a call from my buddy. He decided to buy me am early birthday present in the form of an electronic turbo? Now I've heard of these, but never actually saw one. Anywhere. Ever. I don't even really understand how it could be a turbo. It obviously can't spool right? I looked it up on Google and clicked an eBay link:

Quite a price tag for something that I wouldn't believe to work. He said he bought one for this 5 series and claims it works as described. I don't know tho. what are your thoughts?
