Vortec V8 Stock File Needed

I have a buddy who has a Vortec V8 5.0L that is tuned for E85 and he would like me to flash it back to 87 octane. Can anyone get me a stock file?

VIN: 2GCEK19M6W1112469

Thanks in advance!

No one has a stock file?

Stock file for what ?? Are we supposed to look up your vin to figure out what your talkin about?

Sorry its for a 1998 Silverado 4x4.

5.0, 4L60 or 5.0, 4L80 or 5.0, M/T?? I might have what you need but you need to be more specific.

Sorry guys I'm not use to gassers and I always forget the older ones have the TCM portion part of it. It has the 4L60E.

I am not sure where I got this one. It is supposed to be stock. One thing I noticed is that the 98-2000 Black PCMs don't seem to show the VIN in the calibration.

Awesome thank you sir!
