OK, it turns out that there are two more levels on the EZ that haven't been made known and are going to be removed in future units. By default, they are supposed to be set to level 3 (it says 2 in the manual, though).
Level 5 (the way mine came) is on jumper on the left-most pin on the right side. Level 6 is the middle and left pin on the right-hand side. According to Edge, they are good for the following:
1 - 30 HP
2 - 45 HP
3 - 60 HP
4 - 70 HP, 200 ft. lbs.
5 - 75 HP, 220 ft. lbs.
6 - 80 HP, 240 - 250 ft. lbs.
