I have a i5 motor with a ported throttle body.. cold air intake.. & a header. (The stock exhaust manifold had a CAT) I'm about to get it tuned. Is it normal for the B1 02 to jump around that much? I attached a scan log.

Looks to be a bit slow/lazy, actually. Switching is just how narrowband sensors works. It has to switch from rich to lean so it can find the midpoint to know where it is.
Healthy sensors with everything working as it should will look more like this, instead of your slow gradual lumpy switching.

For being at idle it doesn't seem that slow to me.
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.
