You should almsot tigthen nuts to the correct torque waste of time not doing
IMO if you don't know the torque look it up stupid not to you'll remember for next time
105Nm for the lower torque nut under the car.
20nm for the top nut inside the boot.
Id use a breaker bar to loosen stuff, its possible to break a torque wrench trying to remove a seized fastner thats towards the top of its rated torque, if the breaker bar doesnt budge it, get a scaffold pole over it, usually does the trick .
