Calibration or Codes????

Bought my 97 psd with 3500 miles on it. The truck was the the dealership service manager's vehicle. I did get full warranty and all that stuff. I've always wondered what the calibation numbers ment. The information sticker on the drivers side door jam has the following calibration numbers: 6-89A-R11 this number has a magic marker line through it and above it the following numbers written in black magic marker: 7-89A-R10. I assume these numbers have something to do with the computer program. This truck is an animal, easily pulling my 26ft camp trailer and behind it my, 20ft bass boat, total length 72 ft. legal in Idaho on most roadways. The only mod I have done is adding a 3" down pipe, when I replaced the clutch with a LUK. Thanks in advance for any thoughts or ideas.

When I needed my computer codes for Bully Dog I went to the sticker and even though it was alledged they might be there they weren't. The 'puter codes are 3 letters and one number. Mine for instance are NVK3. I had to pull the 'puter out and check the codes because the 'puter is in a plastic cover and quite naturally on the back side out of sight.
