A few options:
1. Take it to the dealer, have them re-program your pinion factor with the
DRB-III scan tool. Cost about $100
2. Get a Truspeed from Superlift. See:
http://www.4wheelerssupply.com/catalog/product_info.php/products_id/1762
Cost about $200
3. Get a tuner, such as the Hypertech Power Programmer 3, and use it to
calibrate your speedo (as well as tune other performance parameters). Cost
about $300

4. Live with it.. We know that at an indicated 60mph, we're doing about 64..
I believe it's 4% off due to tire size..
Dealer said that it would be 60 to 120 bucks re-program and it would be
"close"..
We told them no thanks, it's already "close"..

"Free" is a relative word, BK.. Might cost a few bucks to drive to Tom's house
and back from Mexico..
Besides, with all the crime and violence in the States, I'm sort of afraid to go
there.. ;-[

Couldn't do it, Greg.... don't have a DRB3 here. If I did, though, I
certainly would.
