Can i use a low/high-imp injector combination?

[Justen]

I think a pfc is what i'm going for. From what i understand, Banzai Racing carries the adapter harness and map sensor that will let me use the FD pfc in an S5... and they'll install resistors into the harness for low-imp injectors for a little extra.

The options we use around this are either resistors, or the FJO injector driver box, this converts the signal to use the injectors as they were designed as peak and hold. More fuel is available by using the injectors as peak and hold.

If I understand this correctly, an injector driver box/module will work better than individual resistors? Only the box will convert the injectors to peak and hold? Or will the individual resistors also convert them?
