FiTech EFI system

I'm considering using the FiTech 400hp system for my 5.9 Magnum build. My camshaft has a 110 degree lobe separation. I have heard that 110 degrees does not work for fuel injection...is that true with these add on systems? I can't seem to find a definitive answer.
Im gonna say the lack of definitive answer has to do somewhat with the blanket statement b.s.-ery involved ;) I have heard of one of these EVER going back for low vac, and that was from someone who heard of someone....who ... heard from some guy...who heard from someone else.
