Can anyone confirm whether or not LS2Edit can make the necessary adjustments after installing different ring & pinion gears? I installed 3.91s and my speedometer needs to be adjusted for the new gears. The Predator cannot do it, it appears that HPTuners cannot do it, but I'm hoping LS2Edit can do it. If LS2Edit can't, what are people with 2005 GTOs and new gears doing to update their speedometers?
Thanks!
Thanks!
