That's a damn fine outfit there. Be sure to have the rest of your combination complete when you order it. They will ask you a bunch of questions about your engine, specific details that is. They will want to know things like how many feet above sea level is the area in which you live. What will you do with the car, racing or street or both and how much of which.
It will be right when you get it. Set the idle speed and go. In my own opinion it's worth every penny. But that's just me. If there was ever an aftermarket company that cared what the product actually does these folks are the ones.
