Hesham's link is working again. I also found this:

The paper comprising chapter 12, starting on page 143 of the conference report, discusses the the SFCS (Survivable flight control system) and PACT flight programs. The PACT program is discussed on pages 155-166 of the pdf and includes performance gains from FBW, reduced stability, slats, and canards.
Just eyeballing the turning performance graph, it looks pretty similar to a graph I remember from one of the early F-15 books comparing the difference between the F-15 and the F-4.
