I dont know too much about TPI systems as Im new and still learning so I will answer any questions as bes as I can. From what I know of the knock sensor is the only thing missing. I will ship anywhere Canada and U.S. Picture are available just Pm me your email address and I will send them to you. Price is $450 O.B.O Thanks
