[soon2Bturbo]

I need some help and input on this since this could be a costly mistake. I'm building a 393 and I want to throw a turbo on it. My question is how difficult is it to use a DFI/FAST engine management system? What are the pros/cons of each? Did you encounter any unexpected (hidden) costs? Please tell me your experiences. I've had a Crane Interceptor before, but now I'm stepping into the big leagues, and I can't afford to goof it up. Please, only knowledgeable, experienced people reply. I don't your story that you heard from a friend of a friend of a friend... Thanks!
