In order to find your axle gears, look at the tag on the inside of your driver door for an axle code, then google the code. The only one I remember off the top of my head is my H6, which is a 3.73 Limited Slip. The metal tag on your differential can be confusing. And as for the price of the programmers; I got my Edge Evolution programmer from truckaddons.com for $399. If you call in when you order from them you can get a discount too.

I assume you have a 4X2 because you would have to do the front as well if it is a 4X4. I'd trade up.
