Ignition module

I am expierencing spark breakdown beginning @ 5500 rpm under full throttle. Car has new MSD Opti, MSD coil and MSD digital-6+. Also new plug wire and plugs. Has anyone had problems with ignition module and would the symptoms be similar to what I am having?

It helps spread out the heat instead of centralize it. And "the more the merrier" doesn't apply here, you don't need much since the are bolted together. It'll just squeeze out all over the place.

Computers use them for CPUs, on their big heatsinks and our rule of thumb is "Paper Thin". Since that actually is pretty thing, even I would dab a bit more on then that

(Since this is electrical related, I tend to dumb it down a bit, please don't take offense if you already knew it. I just don't want someone overheating their new module.)
