Really? You're dealing with torque-steer on this car? We have equal-length driveshafts and an LSD that actually works.
Try turning the DSC/TCS system off via not just pressing the button, but by holding the button down during initial engine startup. If you've done it correctly, both the traction light and the DSC light will stay illuminated on the dash after you let go of the button.
Now, go take off in the car, and tell me what you think. Be careful since all your computer intervention systems (like stability control) are disabled here!
I only experience TQ steer when I'm on uneven surfaces, or when I'm slightly steering and accelerating. You might also want to check your air pressure. 34 cold seems to work well.
