Reading the plugs by the pictures tells a lean story. The only plug that "looks" halfway normal (again, only going by my monitor settings here) is the one on the lower right. Plugs should be a light to medium brown, never white.

I think the stock pistons and rods could take the boost just fine, just tune it on a dyno. Listening for a boost muted ping is to costly of a way to tune such a beast a second time.
