Sorry, the dyno is still meaningless without baselines.
I could show you many dynos similar to yours without a built engine, on less psi, which are equally as meaningless without a baseline.
Here's how a proper dyno looks, with baselines.
My car makes 360whp, on just 10.5 psi at peak. I'm 100% sure my T518Z turbo is not 80% more efficient than your C30-94.
Bottom = stock.
Green = ACN91 5.5psi at peak hp
Pink = E70 5.5psi at peak hp
Orange = 10.5psi at peak hp
