Injection system

So I've been looking on summits an jets sites at a retard set up for boost, but they all seem to say they need to be ran with msd ignition. Am I reading this wrong? I have the mp ignition an the orange box, will I have to switch ignitions to mad to get a retard system to work?
I've also been looking at the 1stage for low boost water methenal injection kit in case I have to switch. I'm only going to be running 5lbs boost but my comp may be a tad bit high. 9.5 maybe.

THE msd BOOSTMASTER is one-piece stand-alone unit that does a couple of things; it replaces your orange/chrome box (is an gnition module) entirely, monitors your boost and retards your timing 1,2, or 3 degrees for every pound of boost it "sees" (the amount per pound of which is adjustable from the cockpit.) Up to a total retard of 15 degrees. You just have to buy a coil.

I use one on my Vortech-blown street-driven 360 and it works well.

Hope this helps.
