Because somebody is going to ask, does it cover the 2019 Silverad/Sierra with the 3.0 Duramax??
This body style started in 2019 and that engine was offered in 2019 to start with.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Can you post up a Stock LM2 read file plz.
Will the global ECM 3.0 LM2 have any support? Ive seen pedal commanders etc for it, but no tuning available. Sucks I have the Global one lol
