Go to Google and put in "5.0 carb vs. FI mpg" and see what the results are. Also ask the forums to see why Mustang guys switch to FI whenever they can... FI is much more efficient.

You are the one who got the same mileage with both FI and Carb right? Well, there is something major wrong with your FI car if that is the case. Again, I see many people getting in the mid 20's with their FI Mustangs. Oh, but they are all just making up their numbers just to feel better about themselves right? Yeah, that's a good reason to spend thousands to change over to a FI system from a carb... And Ford should have saved the billions in research and development to come up with a multi-port fuel injection system that gets EXACTLY the same mileage as the old fashioned carb. Yeah, keep telling yourself they get the same mileage. Maybe you had a 4.10 rear end in your '90 and you drove on the highway in 4th gear.

Well, I don't know what you were doing wrong, but I routinely get 23-25 mpg on the highway in my 4.0 L SOHC V-6 Explorer Sport with 5-speed automatic, with the cruise set at 65 mph. Even better mpg if I'm on state and county highways doing 55 mph. I know you don't want to accept it, but that's how it is.
