As I previous mentioned, the ABI has a 5-degrees difference in induction timing, so there's a very subtle difference in the amount of air and fuel that's getting into the engine, so the bottom end is going to be slightly smoother than the V-Spec, but it's subtle. I also believe that the difference in induction timing gives the ABI slightly better mileage potential.
