I think it's half and half on sicksubies lower boost. The better flowing cams certainly let him flow more air with less manifold pressure + he probably has a small air leak. His afr's still are leaner than I saw on my car but then I have the walboro and that could play into it to.
Anyway, I agree bill should use the pistons for forced induction for forced induction or the pistons for na for na--none of that stradling the fence stuff.

It could be an air leak but his AFR's are telling me otherwise
