So, I got my 4.10's installed yesterday I took my Predator Tuner to change the gear ratio and amazingly there is no 4.10 option, only 4.09. There was the 3.55 and 3.73 option, but no 4.10. What gives? Did anyone else run into this? I figure it is not big deal, but I wanted to see if everyone else ran into this problem.
