I have a 04 gt that has had a motor swap in the past. Before the swap the original owner had bigger injectors and turned the car to those injectors. An original 4v cobra engine was swapped in from a 97 mustang with 24lb injectors the car still has the 2v tune in it for the bigger injectors will the tune make the smaller injectors inject too much gas? The car is running rich, mods are xpipe no cats long tube headers egr delete under drive pulleys
