Sequential Multiport EFI

been toying with the idea of buying a kit but a search here doesn't reveal much about multiport injection kits so here goes, I'm looking at the Eddy proflo 2 kit because the Mass EFI kit is too much loot to play around with , so first off do you guys know of any other kits on the market? second is it really just a matter of a bigger injector and a fuel pump to upgrade the eddy kit from 400 hp to say 550-600 ? my stroker makes 524hp so the basic injector isn't going to cut it . I don't want to go back to school for an electronic engineering degree so I want a simple plug and play setup rather than trying to piece bits together and I want it to be self learning so I don't have to be constantly retuning the darn thing .
