FiTech EFI system

Does anybody run this with a long duration cam? (280+) How are the idle characteristics, I am only pulling 7 - 8 inches of vacuum at idle (1200 rpm)

I have 5in of vacuum at 1100 rpm and starts cold and idles fine. my car has 4 sp so I don't know if torq converter would make a diferance. I took off a fast ez1 pos love the fitech
