An unwanted steering pull experienced in front-wheel-drive vehicles during heavy acceleration. It occurs because unequal drive shaft lengths or suspension geometry imbalances cause one front wheel to receive slightly more mechanical leverage than the other. Manufacturers attempt to neutralize this effect by using equal-length half-shafts, specialized suspension knuckles, or electronic traction management.
That turbo upgrade gave it massive power, but the torque steer will rip the steering wheel right out of your hands.
