There is no difference in tuning a car with an ERL compared to a car with a larger fuel injectors. Fuel entering the combustion camber is the same as fuel entering the combustion camber using 6 fuel injectors on a 4 cylinder car.
It would be the same, if your intake manifold had perfectly equal flow to all four cylinders. Which it does not. With 8 injectors and a properly designed manifold, the effects would be precisely the same. However, with only 6 injectors you run into the same sort of distribution problems that are seen in single fogger nitrous kits. Inevitably, per cylinder distribution (direct port) is the best way to go to ensure equal flow.
On another note, there are actually several benefits from using injectors positioned farther up the intake tract. OEM manufacturers place the injectors at the intake ports for fuel economy reasons, not for best horsepower.

And upgrade your ECM for an aftermarket like AEM's EMS or Accell DFI or motec or anything that actual has a "real time" data streaming/logging.
The AEM EMS has the ability to run staged injection on 8 injectors, so if you went that route you wouldn't need the MF2.

By injecting atomized water into the combustion camber you can run more boost because it'll act as an octane and it'll also retard your timing during high boost pressure.
Water injection allows you to run
more timing because of its cooling effects on both the intake charge and the cylinder temps. Lower temps = less knock = less timing retard. However, it does not act as an octane booster.
