So the SPI header came first. In fact I haven't even heard from MCX... I threw it in there, and now everything is perfect! Got the right amount of boost, noise, and turbolag.
However, SPI "highly recommended" a powercommander, and a new clutch kit.
I'm happy with the clutching I have, but why install the powercommander?
