Do I need any additional boxes i.e. MSD or firewall mounted driver boxes like the other brands?

No, you don’t, others claim to be all inclusive but you have to mount a box on the firewall for it to work and a CDI for the timing control to work. Plus the ECU that’s on the throttle body. That’s three boxes for one system! GO EFI is one throttle body that has EVERYTHING you need in one neat package.

  1. How can I wire an msd ignition box in with my mean street 800hp efi system

    1. The Mean Street needs a tach signal which is available on MSD ignition boxes.
