Hybrid = no boost.
SVT cams is what you'll want for the most power. What are you trying to achieve with different compressions? Might as well stick with stock compression pistons.
As for the PCM, I'm guessing you'll just need one out of another MTX V6 Contour.
Or get yourself some 3L heads & SVT cams and prepare yourself for future boost. What year is the block? I've got some 3L oval port heads that I don't want much for. Let me know if you're interested.
