Here is a log GTO Maf disable.hpl
Set the MAF fail high to 0hz and the 3 MAF dtc's to MIL on first error for speed density tuning.
Other settings can be done depending on if you are tuning with a wideband or fuel trims.
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.
Also operate (speed density) via (os)
Oh , I loaded the base file in the original post .
Failed maf at 2hz
Maf table was zeroed , as a test
Had to keep the STFT And LTFT if not it will not idle , LT were at 50 and ST at 25 .
