I'm actually posting this for my cousin, they did a supercoupe swap (had a whole donor motor but swapped everything onto the mustang engine following the directions in the sticky on this section), but the car simply wont idle its running WAY rich, fouls the plugs out almost instantly and when u pull a plug its SOAKED in raw gas, anyone have any idea whats going on with it. Cars a 97 sixxer.

Its going to need a tune. There is no way it will run properly without one. You are running diffrent size injectors, FI, and all that good stuff. The computer wont be able to do it without a tune. Trust me Im in the middle of doing to swap myself. Ive spent alot of time looking at the M90's.
