I'd recommend swapping the cams out. That's whats holding you back.

I can't really divulge too much about it.

But its the head causing the restriction that is governing that boost level.

NA cams are often not very good FI cams.

I'm not familar with precision turbos at all, but even a tiny gtx2860r will hit 350whp at 20psi. But I'm point to the head, not the turbo.
