Andy - in your opinion what is the right application these days for multiport injectoion, or have these TBI's advanced far enough that there's not much application except for max effort engines?
Port injection gives you better fuel control. Cylinders can be trimmed individually if you run sequential and because you are injecting right at the back of the intake valve, you no longer have to depend on airflow to deliver the fuel. How much better this all is I think is not so much measurable on a dyno as it is in drivability and efficiency. From an emissions standpoint it will run slightly cleaner and should depending on application burn less fuel, not enough less to pay for it in this lifetime but less.
