To do the second set of injectors,
wire the first (primary) injectors into the first injector bank of the MS2. There are two wires for the 1st bank. You will have to combine wires to make them work. Combine injector 1&2 on one wire and 3&4 on the other wire. Injector bank one will control these 4 primary injectors.
Do the same for the second rail exept use the two wires for injector bank 2
When tuning, you are first just going to tune on the first bank. Then when you start running lean (most likely when you are hitting boost) you run the second bank of injectors.
I highly recomend starting out the tuning (or just trying to get the car started, which is going to be difficult enough) on the first rail. Just get a good tune on that.
Also make sure that you have all the settings correct in the MS. Also figure out if you are going to be using the resistor back or not. MS can handle it in both ways but you must make sure to have the correct base settings.
as for controlling bigger injectors, MS2 has fuel control to 1 µsec, which I think is a little faster then the stock ECU I believe
