trunk spring adjustment for trunk with wing?

I installed a wing on my trunk and I find the trunk wants to drop down way too easy. There are 4 slotted holes for the torsion bar adjustment and mine is in the second hole from the front of the car? I am thinking with the wing I need to pull that torsion bar back to the rear of the car but should I go 1 hole or all the way to the end hole?? Also, Is there some danger in doing this?? I was thinking on taking a piece of oak stick and prying it out of the hole and pulling back until it pops back into the next hole? Am I looking for trouble doing it like that?
