The severity of torque steer has a lot to do with suspension design and alignment as well. Power is only one facet of the equation.

Which is why I'd check the bushings at the tie-rods, steering knuckles and the upper and lower wishbones. If any of these joints are on the loose side, the transmission of power through the hub will throw camber and toe out of spec.

PS: I had a problem like this on my GTi. When The steering knuckle ball-joints were shot. They were so loose, that with a hard launch, the hubs would try to wrench themselves against the lower A-arm. As you'd expect..camber, caster and toe all went to hell.
