It is fairly obvious that most automobiles will be changing to fuel injection systems due to the lower emissions. However, unless the cost of these systems decreases significantly then there will still be a massive following that will stick to carburetor. When looking at pure horsepower, the fuel injection system only delivers about 10 extra horsepower at peak. It is the ability to constantly be tuning the fuel and air intake for each cylinder that benefits the performance. The fuel injection systems are the best as they will decrease vibration and help to overcome steep grades that are traditional terrain for off-roading. Again, which one is best completely depends on where and how you're driving. Suggest you go for Fi fuel injection for better power and fuel efficiency.
