    Wow, thank you SO much for this advice, you are amazing! I corrected those tables (I won't say what famous person this tune came from), and its like night and day. Again, thanks so much.

    Yes, is this not obvious? The TCM has a table populated with maximum allowed torque in each gear. Torque is most often considered a load, rather than a source ... you cannot apply torque to an...

    I get that, but I am not asking how the ECU manages torque, I?m asking from which computer does the decision to limit torque arrise when the transmission is overloaded? Does the ECU decide, or does...

    Well raised max engine torque in TCM up to 3000, no change in behavior. It is for certain this only happens in 2nd gear WOT pull... seems to occur right at 3500rpm every time....I kind of feel that...

    Haha, okay, I guess I?m getting warmer? Do you think that value could be causing my issue? Would you mind advising on how I should go about adjusting it? Sorry to be a nag, I?ve worn out google...

    Here's a new clue. I went out tonight and tried to repeat the behavior and catch another log or two... and noticed that I can't get it to happen in a 3rd gear pull, only happens on a 2nd gear...

    Yes, it was Diablo until about 2017?around that time, I converted to HP Tuners to enable update of the calibration for the larger injectors. Prior to that it had a set of Siemens Deka 60lb injectors...

    Yes, this ECU is not original. I got it off Ebay, and I can return it if it is indeed truly bad.

    I can confirm the old ECU was defintely bad, I was the idiot who personally pulled the wires out...

    Thanks everyone for the replies.

    I did notice those injectors not firing, but I assumed that loss of pulse to any particular injector was probably a consequence of another issue... Am I correct...

    Hmm… Does your ECU go into open loop when its in WOT? That would explain the bank to bank injector PW coming back to being equal under WOT, your VE tables are identical bank 1 vs bank 2, which is...
