Again, setup is always a compromise, and it has to suit your driving style. If you're not comfortable with something the car is doing, you can't drive it for all it's worth without worrying about it doing something crazy.
My last TC was a T1FK'05, and my new one is a T3'11 waiting to be built. One thing I've noticed is the cars that were built to run rubber or foam [as opposed to rubber mainly as we have now] tend to have a lot more akermann than
I need or want. I would try going back to a bit of toe out in the front, and if the car is too twitchy, or scrubs a lot of speed in the corners, try reducing your akermann before you try to add any more. It's entirely possible that you'll like the car better with more akermann, but I really kind of doubt that.
Are you running boosted 17.5, or zero timing? Power level is going to have a fairly large impact on setup as well.

This gives neutral steering response on power, and a little extra steering off power.
I agree with this for a small amount of toe-out. Guys that run 1.5-2 degrees toe-out would have to have a lot of slop in the steering to see zero toe on power.
Personally I don't bother playing with toe-in on the front end beyond that. Problems with stability are more often a problem with the chassis or radio setup.
Another good point. If you have it on your radio, expo is your friend.
