I am in the process of installing an on3 turbo kit on my 1999 mustang gt. I have gotten to the point where I am trying to figure out how to set up the vacuum lines for the wastegate and BOV. I have heard some people tell me to get a source from my turbo(I'm not sure how or where to even look for this), while others tell me to get my source from somewhere in my intake. I am really confused as to where to get a source from and how to run it to my wastegate and BOV. Any information would be greatly appreciated. Side note, I've heard people tell me that the stock engine can handle about 400hp. Is that number wheel horsepower or engine horsepower?
