Does anyone have a stock tune file for a 2.8 duramax. I tuned the truck but I need to tune it back to pass inspection.

It won't work because the VIN # is embedded in the tune.

So how would I tune it back to stock?

Which tune did you use?

Did you purchased the vehicle already tuned or you did you buy the tune?

Hd diesel supply, its a tune through efi live.

Did they ask you for the files you pulled out then send you back a tuned update- if so maybe your stock tune is still in your sent mail somewhere.

Pretty sure EFI live saves the original stock mapping prior to flashing the new tune. I would look in your EFI live and see if it is in there.
