I was just replying to the previous poster's comment about weak parts.

The Procal is probably going to be what I get to calibrate my speedo and transmission for when I regear.

I'm sorry. I didn't pick up that you started the thread. With your 37s you should definitely get a programmer ASAP. If you have an auto, it will fix your shift points and speedo. If you have a manual, it will still fix your speedo.

The recommended gear charts are easily found on the Internet. Recommend you find them for the Pentastar and consider their recommendations (in the green area).

Thanks! That's the chart I was looking at, just wanted to double check with the experts (you guys) to make sure a 4.56 is was I need.

Gears and a Procal are #1 priority for me right now. Thanks for the help.
