Looks like no one is jumping to help you.
Either post or PM your VIN. I might have a stock file for you.

How are you able to determine this? Is there a site that tells you what files should have been on the truck "As Built"?

GM SPS can tell you the latest calibration for a given VIN .

GM SDS can tell you the latest calibration for a given VIN .

What is GM SDS? Google search does not show anything. Did you mean AC Delco TDS? If so, how do I do about using this?

That's supposed to say SPS.
I believe you can sign up for an account, then you can access the VIN Information and SPS tabs. Type in the VIN and it will provide information on latest calibration data.

I am facing the same problem. Does anyone have the stock TCM tune for a 2006, 1GCJK332X6F103753? It would be much appreciated.

Hello, I think I have exhausted all the resources I could find. I try to do my best, to not post a question, when the answer is already in the forum. If I missed it, I apologize. I just received my flashscan V3 today and learned my first lesson, the E86A ECM is not readable by the Flashscan. I am searching for a base file for my 2011 LML E86A. VIN is 1GT125C88BF192829 and if you need any additional info, please let me know.
Thank you!

I installed a DSP5 tune on my 06 LBZ (VIN 1GCHK23D26F1449023) several years ago. Comifornia tightened the smog requirement's and it is now reading the tune in the computer. Does anyone have a stock tune?

Thanks,

That VIN has one extra digit. Is the an extra 4 in there by chance?

Assuming I got the VIN right, this is the correct file.

Hi I'm also looking for an unlocked stock tune file for vin 1GC1KVE80GF193235 All I'm trying to do is adjust the speedometer, but it seems a flash is required for that. Your help is much appreciated.

I am just getting started in the diesel tuning world, and I am having a difficult time learning what tools to use to build files. I am currently tuning a 2015 Duramax with a E86B ecm, VIN: 1GC1KVE8XGF131180. I noticed that you were able to generate a base tune file pretty quickly. Is this because you are using some sort of file generating software or are you building the file in Scan and Tune v8? I would appreciate a base tune file, however I feel that it would be more beneficial for me to learn the method so I am not dependent on forum begging to get these files. Can you share your secrets with me?

No secret. I was lucky enough to be around in the days when the OEM LML files were plentiful.
If you have access to the database, use TIS to lookup your VIN and select the segments as needed.
If you can't find one, hookup to the truck with GDS and grab the calibration cache. Then use the built in EFI tool to build a calibration file from said cache files.

i can not find the stock file cm2200. E/C=(CM90012.07) to save my life. looking for a deleted or true stock tune file if possible. VIN 3D7UT2CL1BG544442.
it makes it more difficult i think because its a G56. ive found a few but they arent true G56 files. im looking for files without the 68rfe tree in the calibrations tab in edit(F5). i am willing to pay for the file(s)
