Another MS Wheel settings Question

Hi folks,

as of two days ago I went out and purchased a HORI MS Wheel EX2 for the 360 due to being on a budget.
Since then I have tinkered with the wheel settings to keep my cars from swerving/sliding when on a straight. I haven't had much luck and it's kind of frustrating really. ended up resetting my setup for the time being.

I was wondering if someone out there would know a good setup..

Current driving aids in use:
TCS, Manual, Normal steering, and brake line.

I have tried simulation steering and that doesn't make it any better.
