    I did it right away, but it still doesn't help. The algorithm for enabling the editorial remains a mystery

    I experienced several variations on dragstrip, I liked this one the most. Upshifting is normal, but artifacts appeared in the form of a hump (Highlighted in a circle)
    Of the minuses - big loss of time

    Funny enough, my stock transmission turbo 300 has a similar 2-3 and 3-4 slight rpm flare (not audible in the video below though). I just assumed I'm on the edge of what the transmission can handle, but it seems to happen right after the shift is completed.

    Now the transmission has stopped flaring like you showed. Must have needed to just relearn through daily driving.

    Just ran a 10.7@128mph with a stock NAG1. The 2-3 shift isn't flaring but it takes a bit to complete now. Other shifts are good.

    I don't understand how you do it. I have 10.5 (145 mph), the transmission is hard. she did not die, but I decided to take it off and check it, tomorrow there will be a result. I stopped pouring more power, everything goes into bad shifting 3-4.
    in addition, I made a new torque converter for stall speed 4000, let's see what happens. while best 60ft 1.9 sec. I know it's sad)

    I think your tune needs higher ramp torque values. Thats the main thing that improved mine (I doubled the high end values from the srt cal). Also you have the torque converter locking up in 1st, disable that.
