should I use ballast resister with msd blaster 2 coil

Hey guys. Putting a blaster 2 coil on my cuda & instructions are not real clear if I need to use included resister(.80 ohm) in addition to resister on firewall. My setup is mopar performance distributer & chrome ignition box. All instructions say are its needed with points & not needed with modern electronic ignitions but then they say its needed on some of msd's boxes. Thanks for any info.
