We had many threads about this already, and it goes in the way same all the time. I think unless someone proves the TF34 is underpowered, ED won't change anything (even though Yo-Yo last year said TF34 in DCS had issues IIRC).   
And I honestly don't know, Yo-Yo explained many times why the TF34 does not reach higher ITT values. I'd be sad if it's true though :(   
Also, we don't really have many tools or ways to measure the force (i.e thrust) produced but the TF34s in DCS, so measuring that would be quite difficult.
