If you have cats, the AFR can dip while in COT (cat over temp) which is done to protect the cats. So you usually tune for the .82-.84 I mentioned with COT turned off, then turn it back on when you’re done tuning. So it’s important to know what you’re looking at in that regard.
I would consider .82 very safe on an LT4.
