Your airflow model is way off if your fuel trims are at +25% all the time in that log. Also your running too much fuel at WOT per the commanded AFR and what that wideband is showing.
Plus you are way out of injector at that commanded AFR value, it's way over 100%. You need to fix the MAF and VE to bring the fuel trims back in line and you should start commanding and AFR around 12.2 to see what it does for the injector duty cycle and knock.

If you don't post your tune and logs when you have questions you aren't helping yourself.
Is there a prize for starting multiple threads I'm unaware of? These things go more smoothly if people just continue their existing threads so they can be built on.

Cool, well then fix the VE.

The fueling is a mess on this.. Everyone has already saw it.
I don't see a problem with knock.. At the end it did the MAX retard thing like it has a knock sensor code pending.

Fuel pressure problem.
Actually. Is that even the right injector data?
