I need a T42 stock tune (2008 Silverado, 5.3) that uses OS 24252617. If anyone can point me in the direction of one I would appreciate it, thanks.

Ive looked through all my stock tunes and i have every OS but that one...
You sure that's the right year/model/OS? I was bored and looked up calibrations for every gas 2008 Silverado VIN I could find and every one from the 4.3 v6 up to the 6.0 all had the 24239927 OS.

You're right. The module that came with my truck (and I believe to be faulty) uses that OS. I bought a replacement (online) and when I tried to load it I got an error looking for the OS I posted. I thought maybe the new module was a different OS for the same year truck but I haven't found that OS associated with the year/model of my truck. Now I'm thinking I have the wrong module. I read the file from my old module, so now I need to find the right module (I think). Thanks very much for your reply.
You can refer to https://tis2web.service.gm.com/tis2web with the VIN from your vehicle and see what the correct calibrations are. Or if its a project vehicle, you can use the VIN from the ECM (if it is correct!).

I don't think you can brick it. You will have to write all 4 modules though, I've never checked with efilive stuff though, sry.
You SHOULD be able to full flash the tune you read from the original TCM to the new one. I don't think the T42's have the same restrictions/risks with regards to OS compatibility that newer modules tend to have.

Okay, here is what I get when I try to full flash the new module. Am I doing something wrong here?
