Wow...that is a beautiful set up. That would look very cool on my cobra......if I had the extra cash! Pretty penny but I am sure it is worth it.
I was just watching "horse power" TV this past sunday and they had a fuel injection system that looked like a carb. They were installing it in a 66charger. It had no return fuel line and you had to run their fuel pump in conjunction with the mechanical fuel pump. They said it couldn't handle over 500 HP without a return line however. They too claim that the system self tunes but that you can plug a lap top in if you want via a USB port to tune as well. The A/F sensor is what "teaches" the program.
Here is a quote from their web site:
