My son and I just finished up a tbi cinversion in his 1972 GMC truck, put a vortec 383 engine and 700r4 trans. The truck runs rich and we are haveing problems finding a way to see live data. Does anyone have any recomendations. I had a old scanner with the correct adapter to a 25 pin and then to usb but cant get any recomeded programs to work for us to diagnose the issues, Thanks in advance
