I called one of the reprograming ECU companies and he told me to ask a mustang guru on the internet if the swap would work? If i make the swap, does it just plug in and away we go? or do i need to reprogram it to match the car?


That'll get you 5 hp.

You'd be better off going with underdrive pulleys, a K&N drop in filter, and get a chip.

you can reprogram or chip your current computer, for FAR less time, money, and aggravation than replacing the ECM.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
