B6 Torque steer

[Austin-1275]

All,
Any ideas why I get torque steer left when I nail the throttle.

I have a B6D setup with LRP 8.5t running a laydown box and gear diff.

When I feather throttle its ok but on hard acceleration it pulls left badly.

Ive stripped it down to check for poor or incorrect setup and all is consistent.

Any ideas.

Thanks
