Any one have this trouble with a big cam?
seems adding after start enrichment will not help?

Command afr is asking for a rich start.
my driver side 02 sensor is reading around 100mv lower then the passenger,The wide band is on driver side as well
Tune and logs for if you want people to look and see what may need adjustment.
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.
Tune attached. i will get a data log.
02 z06 with btr stage 4 cam.
Tune was from a car with same set up. I have been adding some timing to work on drive ability . Other then the usual bucking and a large dip in rpm when when car is in neutral coming to a stop its pretty good. (has 10 lb flywheel and aluminum fluidamper)

Those o2s aren't doing a thing at idle. Probably not faulty, just not setup enough. Presumably they switch during cruise... (I hope)?
