Mustang, 2005 GT V8 project questions/help, ecu software

[Kat79]

Really need help to get our mustang on the road!!
Anyone know anywhere best in the Uk/USA to contact regarding cloning/programming a Ecu (which has matching numbers to old Ecu).

Cumbria. We have a guy coming end of week with some other software to try, didn't think would be this hard!
