I show you're off by only -2.31 mph at 70 mph. Tire revolutions per mile
went from 659 to 637. Whoever has a '01 FSM needs to check whether the new
number is a choice and if not, what the closest to it is. You may be there
already. If there is an allowable change you may want to check with DML'ers
in your area that may know a mechanic that can do it cheaper. Bernd or
Richard Pyburn come to mind.

Subject: DML: DRB programming for new tires
I went from 265/70/16s to 265/75/16s on my '01 Dak. According tire
calculator my speedo is off about 4 mph @ 70mph. That's not too big of
a deal, but it sucks that my overhead computer shows about 2mpg less
now. I was hoping to know the true mpg with my new, bigger, heavier
tires.
I went to North Star Dodge (San Antonio) and they said it would cost
$68. I told them I thought it should be less as it should only take 5
min or so. She said they have to charge a full hour of labor, so I said
see ya.
I then drove to Fiesta Dodge (San Antonio). At first they guy told me
it couldn't be changed, then he said I need to come back with the
revolutions per mile and it would cost $69. He said the process takes
about an hour. Again, see ya.
I called Crenwelge Motors (Kerville, where I bought the truck). They
said they have to plug in the DRB, drive the truck with it plugged in,
then spend time programming.
I had read on another newsgrougp (can't remember which one) that someone
had this done for $30-$35 bucks. Anyone have advice for me?
Sorry for the somewhat long post.
