In general the cam needs 114 degrees lobe seperation angle or greater and less than 216deg intake duration @ 0.050". Some cams with much shorter intake duration(208 degrees and below) and 112 LSA are also know to be stable. Cam lift doesn't seem to make much effect.

so basicly your cam needs swapped out. or you need to convert to mass air. if you would rather convert let me know i have a conversion harness for sale along with an MAF meter. just send me a pm

with sd. the injectors are batch fired not sequential so it doesnt matter what cam is in there as long as the plug wires are matching that firing order.
if this was a stang or MAF already then injector order would need to match

are you talking in a truck or mustang. the efi is different between the 2 and so is the wiring harness. check out FFI.com
