As part of your spark work, take a look at this: Engine>Spark>Retard>Static Retard>vs Cylinder (that is a button) table. This table causes false KR and some professional tuners do not fix it. IMO this table should be all zeroes.
Has the TCM been unlocked?

It's an AEM fuel/boost psi gauge that I've plugged into the procharger manifold breakout block. Unfortunately, I don't have it logging anywhere. So it just reads instant and peak on the gauge.
I have since ordered a DSX baro breakout harness and a 3 bar MAP. Waiting for it to get here.
On the boost PSI issue, going to take a look at the PCV valve today. I heard that some of the pre-2019 engines didn't have a check valve built into the PCV valve. That could be bleeding off some manifold pressure into the crankcase. The PC kit I ordered from Jegs was supposed to fit 2016+... ended up being a 2019+ kit. Talked to a few people and sounds like the biggest difference is the kits for 2016-2018 included a check valve for the PCV. Hoping that's my problem, would be an easy fix.
While on that subject, the 2019+ kits also just delete the driver side aux radiator instead of relocating it like the 2016-2018 kits do. Haven't seen any negative effects of removing that rad. I imagine it would make a difference if I were racing on a road course where it would be pushed harder for longer.
Thanks for the head's up on the static retard vs cyl. I don't hear any audible knock at the points where the scanner is saying I am getting it. It's also at the point where the PE goes away (see previous posts), so will fix the PE at high RPM first, then take a look there.
I do not have the TCM unlocked. I may do that over the winter when I wont be driving as much anyway. It's still my summer/fall toy and not wanting to wait a couple of weeks for the unlock. I'll need to have it unlocked eventually since I'm planning on doing a torque converter with a stall. Also wanting to increase slightly, and make consistent, the shift points.
Anything else with TCM tune I would want to change?
