I?m trying to put together a list of settings I must change for my attempt to tune my MAF on my Silverado. I?ve found a wealth of info about tuning the MAF on this forum and on YouTube and I think I?m going to be able to pull it off. I?m not able to find any info as to whether or not I should set O2 related DTCs to No Error Reported or is it okay to leave them all as is while testing. I?m not removing them physically but I?m removing their input via the tune I will use for tuning the MAF. Any info greatly appreciated!
