I think it’s because the 41% torque rise is measured from rated speed back to peak torque.
The old engine had a much higher rated speed of 2100rpm and it’s not fuelling hard up there so on paper it’s measures a 41% torque rise back to peak torque.
In reality driving it at 1900 you wouldn’t feel that
