    Watch your timing, 25* at 0.81g airmass might get some KR, but I don't see any.

    Which wideband are you using (is it on bank 2)...?

    The MAF plumbing is basically stock. It has the stock intake tube that connects the MAF to the TB. In front of the MAF has a stock TPI lid as the car is a thirdgen Camaro. I will say that I HAVE disconnected the lid so the MAF was to free air as a test to ensure that was not the restriction.

    I have not had the car on a dyno, only logged it on the street.

    AT WOT I do not have any KR. Originally the tune was at 26.7* and I lowered it to see if there was any performance difference - there wasn't so I left it at 25*. At the higher value there was no KR either.

    I have an Innovate LC1 connected to bank 2 in the y pipe. ~16" from the collector of the longtubes.

    With all that said, again why would the spark fluctuate when there shouldn't be anything that would pull timing? Stock OS, there are no issues. What is in the spark table is what the log reflects. This issue is only present in the COS and in SD(have not tried with COS with MAF connected, as that was not the plan...).
