I just got my 4.56 rear diff in, and just bought a yellow box. I searched and I couldn't find anyone that posted their actual differences in percentages or what their calibrations were for their car, if it be 4.44 gears, 4.56, 4.57, 4.77 which I think might help some people out there that might not have a GPS or anything like that. Maybe we might be able to stickie this if it would be of use to people. Thanks you everyone and thanks mods for letting me post here.

 

You really did not look that hard. There is a FAQ stuck at the top of this forum, with a ton of great threads. This is just one of them.

Yellow Box Settings?, I'll show you mine, if you show me yours

 

Slam dunk!

 

I prefer: Pwned!!1!
