Actually no, the same engine skills it takes to tune a carb are used with FI, difference is the laptop is the tool, the same way a screwdriver is a tool.
And Rusty, you are a good guy, but you can’t have it both ways. In post #175 you say you don’t have the skills to tune a throttle body FI system, however in post # 170 you say the lap top does all the work, implying that you do have knowledge on how FI is tuned and the part the laptop plays in the process. I am inclined to believe post # 175
And that is Ok, to say again what about everyone that has made a positive comment about FI has said, run the fuel system that you choose to. It’s your car.
