Pretty safe to say that if you are using one of the higher end EFI systems, John had his hand in its development.
The one nice thing with the BS3 is if you have a computer controlled auto trans, you can control it within the one ECU. So in this situation you would have one less controller to mount. The down side is though it is in one controller, the cost would still be the same as a FAST and TCI controller package.
