I have two M2s. One is GP500. The other one is the abuse car (FBO, meth, ethanol, PI, stock turbo).
Other cars I mentioned, not my cars.
More ethanol = more octane, but =\ more boost. I'm sure Raymondo can agree in his case as well.
The 11.11s N55 does 25psi maxing out PS2 with E40 and meth. More ethanol does nothing in his case.

I agree too, more ethanol doesn't mean more boost. But it can allow you to run more boost and timing vs. pump gas or lower concentrations of ethanol alone.
The reason why it can make 25PSI on E40 is because he has meth to supplement octane, that's essentially the same thing as running more ethanol content, but it is easier on the fuel system if he doesn't have the setup to flow more fuel for the higher E content.
