Sorry the issue is that HE IS RUNNING A MOPAR BREAKERLESS ignition WHICH MUST USE a ballast resistor.
Also you might want to correct your post. ???MSD alternator??? Whut?
Not sure about the Sniper, but on the FiTech it won't work correctly(that's what FiTech told me). I specifically addressed that with them as I was running a Proform with a 6 pin module before going EFIOP.........I mentioned GM HEI module earlier. One other advantage of HEI is if you use one of the 6 pin modules, you can use the EFI to control spark advance
