5psi and going lean will kill a 6.0L. But then again why would nelson, who tunes vehicles himself let it go lean?

I'd think that a fairly good compression ratio would get the 500 you are looking for. Something like BigTex is doing. Whitt1 might also be onto something, going with a 90mm throttle body to prevent the supercharger pulling a vacuum on the inlet side of the blower.

Just some food for thought.
