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!

tire size and gear ratios are changed in the speedo scaling screen on LS2edit. Another option and an INCREDIBLE programmer is Bryan Herter at pcmforless.com. He also has a GTO and a loyal customer base. I have had about 5 vehicles programmed by him. Always perfect. A little reading on ls2edit is in MARCH 06 GM High Tech.
