That is how I have read this:

I dont read, i use osmosis. duh! lol. Ok on a serious note I read that as to the center differential is a locked unit @ a approx. 50/50 split. Now this split can be manipulated through different gear sets, but to my knowledge there isn't a unit that has been engineered to be manipulated in such a way. Excluding the cusco unit as even that differential has its limits as to how it will split.

The Evo center diff is basically the same thing as a limited slip differential in a 2wd car. The 8's have a viscous diff that acts the same all the time. The 9's have a clutch-based LSD that varies the pressure on the clutches (but has the same pressure on the F and R clutches) based primarily on steering angle as far as I know.
The point of an LSD is that it can send power to where it's needed. As one set of wheels moves faster, it gets less power. So yes, the center diff moves power/torque around based on where it's needed.
The 50/50 split that everyone quotes is that if all four wheels have traction, it's distributing force equally among them.

I didn't read anything but the OP.
I've noticed in my car, when I use my Z1's, I usually have a very slight and sometimes frustrating understeer when I add WOT too early on corner exit. I think this may be due to my driving habits and expecting too much from the car. Now when I use my all-season coopers and add WOT too early, I usually have a nice, fun, sweeping corner exit oversteer. From what I've read, grippier tires will almost always results in slight understeer, and I've experienced this first hand. You just need to change driving habits.
The Evo is very sensative to weight distrabution. Trail-braking makes corner entry very fun, and in some cases, lifting or braking to hard into a turn can cause a spin. That's just how they are. Evo's are tail-happy when driven a certain way, but any car will understeer if you throw it into a corner the wrong way.
Take some time to learn the car, try making slight adjustments to driving habits and see how it works for you. Once you've done this, then decide if it's time to fix the problem with mods
