I need to get the OS and all associated hardware for a 2015/2016 LML since TIS seems to be either hidden or no longer since the LML trucks are flash only. This truck has a trash tune and just looking to go back to 100% stock. See VIN info below.
VIN: 1GT120E86FF677119
GMC DENALI 4D, 4X4 STANDARD BED
DOM: 09/16
Currently have a stock file for a 15.5 LML but can't tell if it will be a mismatch as I do not want to cross LML OS's. The one I have for a different truck of ours is listed below.
OS: 12667378
Engine OS: 12666850
Engine Diagnostics: 12666622
Engine: 12667404
Fuel System: 12667412
