Yeah, I can definitely calibrate the speedometer with the Xcal 2.

The $400 was just for labor, not including the installation kit, gears, or fluid.

I was told it would be safe for me to go with 4.10 with the automatic, but I would lose gas mileage. Since I do drive it everyday, and on the highway, I think 3.90s would be the happy medium to go with.
