Torque Steer?

[Nix, Jim]

1991 200q20v 
The problem I have is that under hard acceleration, the car drifts to the left.  Let off and it goes to the right.  Check or replaced motor mounts, snub mount, sub frame mounts, rear suspension mounts, changed diff fluid, checked all the suspension, steering and hub bolts.  Used a 2x4 to check for play.  Even tried different tires.  The car is set up for racing, so it has been lightened.

Is there anything I'm missing?
Thanks, Jim
