It's an immense amount of work to pull something like this off, even if you do have some resources available to you. Odd that he chose not to use the stock ECU for this project. Maybe R/T will do a road test of the Ugly horse when it's done.
I had mentioned in my earlier post, that I had come across other ECO-boost Mustang swaps. i should have bookmarked those, cause I have tried to find those again, but have come up short. One is an SN95 and the other an SVO?
