    I think I follow you...
    You are saying if stock TB, Intake, and a previously fine tuned MAF sensor you can adjust your new (cheap) injectors based on fuel trims...

    Now he has changed Intake, TB,...

    Not sure I'm following your here...
    You say 2000 cc flow rates, per MFG data, then adjust from there. Is that adjusting based on PSI? Fuel Trim data?
    Are you manipulating MFG supplied data for...

    What do your front o2's read key on engine off?

    I guess you could swap o2 side to side and see if the behavior follows
    Right now it looks like bank (2) o2 is dead

    Filters keep your data more accurate. So that could keep you from chasing your tail.
    Your discipline with your right foot does too, LOL...

    I'll work on some basic filters for ya and send them...

    Injector Tip Temp is not on GEN 3
    It is pretty important on GEN 4 as its an offset in injector data (Basically an adder to deal with heat soak).

    On the o2, good possibility...

    Okay, Next we...

    Here is a log of mine. You can see they are lazy at idle/low RPM but they are somewhat consistent.
    Follow the log to above 2000 RPM and see they almost mirror each other

    For the most part yes.
    One might go low/high for a bit, then they other might. But in general they should be pretty consistent.

    And in your log with them tied back together, 2 seems to be bias rich.
    1 trims somewhat normal

    So this is from your first posted log. See your AFR table showing rich.
    Notice your o2 bank 2 pretty much flatlined rich, agreeing with your wideband...

    Okay
    Let me get a good picture of what I see. It might not be right but its worth looking into.

    When you say you are spot on with your AFR, are you looking at your fuel trims shown in this picture?
    Cause the log this snip is from. Your MAF is about 7% rich (Its using your "boost Math" which...

    I didn't look very close
    I'm guessing when you tune them individually you are open loop with wideband in bank 2?

    Then when you put them back together you go back closed loop?

    Log appears to be better, but I see the same think.

    Look at your o2 on bank 2 sensor 1 it never moves more than a few points idling or on throttle
    Bank 1 sensor 1 moves normal on throttle, but...

    No I don't think that will bring them closer, I think both will just read richer.
    Does your wideband gauge match what scanner reads?

    What I'm seeing is your o2 errors in the log (STFT + LTFT) are...

    What Codes?
    Some codes require multiply "events" to occur before they will go ready, no way around it that I'm aware of.
