THANK YOU! I appreciate it!

Now I just gotta figure out what to change and what not to change.

 

Only the tables that differ and reflash the whole OS.

That was a stock calibration and appeared to be from a 4x4. You might have to turn the 4x4 stuff of so you don't have any codes.

If I get a 2 wheel drive Vin number from a 2002- 2500 I might be able to get the Gm calibration and read it out in HPT.

 

Sorry for getting back to this late but I just got my truck back. It was on loan to a friend. Anywho, So I tried using the file and I had a VIN/OS mismatch. HPtuners fixed to where I could use it BUT I need to purchase a license. So I wrote the whole OS in and then tried to write the calibration from my truck into it. I think though I may have it backwards and need to use the 02 OS write/import the tables differ and use that. Anyway that's where I'm at the truck's dead and not happy with the 02 OS. Can you confirm 1FastBrick?

Sorry for Necromancing the thread.
