Pardon My english thing is that my brother gave me his supercharged 3.8 v6 mustang and its chokes when running hard or goin on steep up hills until u accelerate it over 6some rpms thats whet a cloud of smoke comes out of the back. I was told that it needed probably new injectors because of some prob with fuel mixing wrongly, it has 24 but was thinking of getting 42, I also need to change the clutch should I get a stage 3 or just use a stock replacement. Its an every day drive + want to take it to the race track some times. by the way the computers not modified.
