Hello fellow EFIers. I was talking to Marino this mornig at Pantera east (Florida) and they are selling the DFI (I don't know which model) for about $800.00 U.S. You can reach them at 813-381-1151 This comes with an O2 sensor and a MAP sensor and I believe this is a batch type system. Marino seemed to be very helpfull. later jw
