torque sensor replaced, slight pull right
 

good day, I have a 2011 escape that the steering lost the power assist, So i changed the torque sensor. plugged in a computer to the vehicle and walked through the procedure to recalibrate the steering, spun steering fully left and right etc. and satisfied all the prompts on computer. Now I have the issue that the vehicle has a verry slight pull to the right and very easily turns to the right and turns to the left as it did prior to changeout. Question is what would find center again and how do i correct the steering imbalance regarding turning assist.
