From what I understand, the XFC will be the ticket for allowing that without even running extra injectors. All that is needed is to run with an boost-referenced FPR (which I have) and the normal timing controlls and such.
If I go the Megasquirt way, I'll have to add an injector or two, but the price deal is sweat for those systems...
So far, the XFC is on top of my wish list.
