I'm getting 3:73 gears installed tommorow, I can't find on the Sct2 how to flash the setting for the speedometor for the new gear. I also have a predator tuner the directions are easy to follow but I don't want to mess up my Sct2 tune, can I use just that function on the predator without harming the Sct2 tune.
This probably sounds stupie but I'm new at this tuner thing and don't want to screw something up.

Thanks for any help.

I just had my gears installed today. I got my tune from Lidio at atlernative auto. I sent my tuner back to him so he could put the correct data for the 3.73's on my tuner. He not only changed the speedometer, but I think he also changed the way it would shift. I don't think you wanna use another tuner at all. Maybe someone with more experience than me can chime in here, but I'm not even sure that would work. You will like the gears. I just drove mine home today. I didn't really get on it, but I could feel a definate difference.
