Fitech and boost

View attachment 1715093331 This is my buddy's 1988 D150. Twin turbo 2x4 Fitech 318. Stock bottom and with thin head gaskets about 9:1 compression. He is running a 6A controlled by the Fitech. I will try to answer any questions.
Using full timing control via the fitech correct? How long has it lived on the street and how much boost?
