420a powered cars use High-Z injectors, as I recall, so impedance shouldn't be an issue.

It's more a question of: "Will they fit my fuel rail and head?"

I *believe* your stock injectors are rated at 19lb/200cc. A 125% increase is pretty significant, I don't know if you can dial that much out with an AFC. (Bear in mind that I have no experience with that particular tool.)
