I'm sorry but I'm having trouble understanding your post. I never said anything about it coming from the factory.

To the OP have the dealer purchase a ProCal for you and use that to reset the gears and tire size.
did you miss the last half of my post?

you wrote this.

"this cant be true. let me share what happened to me.

I bought my jeep brand new off the lot thinking I had 3.21's. after installing 37's I found that it really wasnt that bad to drive. something had to be up, so I checked my build sheet. sure enough, I had 3.73's! for some reason my jeep came with a procomp branded hypertech programmer that tunes the computer for gears and tires. I changed the gears setting from STOCK to 3.73 and now it drives a hell of a lot better. shift points are just beautiful"

The "for some reason my jeep came with procomp yada yada" threw me.
If you would have replied for some reason the dealer included it then I would have understood.
