Finally got my wideband hooked up and logging so I did two short datalogs today. One is just a short idle and the other is pull from 10-90mph. I see some knock and also seems to be running rich but I'd like to get some opinions on everything.
P.S. The wideband seems to be logging .1-.2 leaner than actual.
7-3-16 first with afr.hpl

Notable mods are mild cam, XSPower headers, Gibson exhaust, LS1 fans, built trans with 2800 stall.

The idle fuel trims are still pretty negative, you could touch up the ve/maf to get that closer. And mid 11's is rich for a NA motor.
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.
Thats what I thought. I probably should shoot for low to mid 12s for AFRs? Also, think I should reduce timing a bit to get rid of the knock?
