Default Ignition?

Hello all! Mods are in profile. Im curious to know at what point should you add an upgraded ignition like the MSD multi spark unit. On top of all of my mods I am now running a Procharger D1-SC with 9lbs of boost.
I am haveing an issue when I stomp on it. It blubbers. It doesn't seem to do it if I gradually step down on the throttle. Fuel pressure is good and I am adding 24% more fuel at WOT. Could the sudden charge be screwing up the spark? Plugs are gaped at 35 thousandths.

Well I installed a MSD 6-AL ignition box.I thought it might be a problem with the spark, no luck. Although I wasn't sure how to wire it because there diagram that shows how to wire a dual connector coil shows four wires. Mine has three and the colors of the two don't match with the diagram. So I wired it up like they show it but without the one wire. So I'm not sure about the wiring but it's got spark. I also have a new opti on it so I don't think thats it. Fuel pressure is good.
Come on guy's help me think??
