Timing and I_Avg look excellent and consistent across all cylinders, so plugs must be working as intended.

Might be able to use some duty bias turning at the top end where you are a little under target, but I'm not sure your turbos have any more to give as PWM is nearly max.

How does it look post shift? No PI or WMI so fuel pressure will be the issue I think.

Yea I sometimes under WOT get a injector fuel shutoff code? Possible hpfp not supplying enough pressure? It will happen at shifts I overboost alittle too. Do i just have a weak hpfp? It's 2 years old the lpfp is stock (well a Chinese knock off).

Take another log if you can 3rd gear, redline, shift into 4th, and stay in it as long as you are comfortable.

Curious to see post shift timing & fuel

I don't see the fuel system shutting down in that last log but it does appear that you are pushing the limits of your HPFP.

FYI...best to just post and discuss one log at a time...if you make it too involved, complicated, people will just pass it by.

Do you Think my AVG_IGN is increasing on the post shift logs due to the HPFP lagging? Btw the HPFP is only 2 years old the LPFP is a stock chinese made one from 2 years ago.

I just wonder why my AVG_IGN keeps raising on the shift logs but lowers when single gear pulls and what I can do...

Could be due to knock or false knock. If you believe it's false knock, see if the KR map improves it.

Correct me if I'm wrong but I do think it's false knock but running those maps are riskier correct? I would rather be on the safe side tbh...
