hi i have a 2001 mustang gt..it used to have supercharger on it was taking off before i bought it..i noticed the car is running rich baugs down no throtle response..it has 42 lbs injectors a diffrent computer and a mass air that has been calibrated with the number scrached through it...get about 135 miles to a tank of gas...ok i found a wrecked 2001 mustang gt stock swaped computer,mass air and injectors but cant get the fuel pump to come on...and its a automaticcomputer some say there the same some say there diffrent..just wondering what i need to do to get it back to factory..the only thing supose to be done is a billetintake.. but u know how that goes..

 

vert and coupe computers are different and not interchangable. What do you mean by the car had a different computer?

If it ran with the old computer in then put it back in and keep the stock MAF and 19# injectors then take the car to ford and pay them to reflash the computer. Problem solved.

 

what i ment as diffrent computer isnot a stock one
