I have a 2009 GMC Sierra with the old OS# 12626014 that EFI LIVE is not supporting apparently per support. With that being said, Support said they are only supporting the OS# 12630501. Does anyone have a STOCK file that matches the new OS?
Truck is:
2009 GMC Sierra SLT
CC Short Bed
2WD
6.2 (E38)
6L80e (T43)
VIN# 3GTEC33259G100048
