    3.73's

    I got my car back a few days ago from the cam install and tune and they said that it was tuned a few years ago with 3.73 gears. I didnt know i had gears. And i noticed when my car is coasting it kinda whines. Is this due to the gears?

    I didnt really notice it but since i got my new tires 4 or 5 months ago i now notice it. But my tuner said that it sounds like when you drive it, that it has 3.73 gears. I take that back it doesn't really whine it kinda whistles.

    I have installed both Motive and GM gears. Never had them whine if you set them up right.
