gen iv 5.3 2007 silverado , i could be tripping BUT

i think im dealing with a fuel issue of some sort , maybe afr ? im definitely new to all of this tuning shit so please bare with me .
everything mechanical is recently brand new .
so i have a bunch of deletes , such as evap ,pcv and the fuel pump control module , crankcase is vented to atmosphere aswell .
just today i adjusted the tune from going to return style from returnless , i adjusted (flow rate vs pressure ) to match all across the board and just simply set psi parameters to the (58)

the regulator is set to 58psi aswell now thanks to some help that i got on another post . , i was initially running at 43 psi after i did the fscm delete assuming thats what the fscm commanded when it was still installed .
after the adjustment today it feels better , more responsive and smooth , but theres a slight fuel knock i think , only at first second or two at cranking .
and even after the progress today, i swear i still feel like the full power isnt there , if anyone could check my tune and log that would be greatly appreciated , i have no idea what im doing unless i have a wrench in my hand

It would be a lot easier on you and everyone trying to help to just stay with one thread, at least until something drastic changes. Keeps you from having to explain everything multiple times and allows everyone to follow along and not ask the same basic questions every time. And it’s all related anyway.

Did you flash the tune just before you took that log? I'd try to get at least 20-25min logs. Add Dynamic Airflow to your channels. You can give this a go and see if it feels any better for you. Your trims were showing pretty rich for the most part but did see some lean areas. MAF & VVE tweaks were based on that log.

What problem are you trying to solve? Where in the data log do you perceive a problem? If it feels like it's down on power, where in the data log were you doing a WOT pull?

Why do you have your crankcase vented to atmosphere?

return or returnless dosnt change anything, its if the fuel rail pressure is set to constant 58psi or its set to base 58psi and referenced to manifold vacuum/boost, if ur a constant 58psi then the IFR needs to vary to suit
