Not sure if anyone is running sequential injection on the 420a yet, but its running excellent, smooth as silk. I basically made my own circuit board and harness and did the ms board mods. Setup is 4g63 injectors, resistor pack, and ignitor module. More consistent cylinder fueling has netted less knock potential, and more consistent afr.

fuel injection)
