    6L80e not shifting on time

    I'm tuning my buddies car, its a 2011 Camaro ss 6.2/6l80e, it just has intake, headers and exhaust. I'm having issues with the transmission not shifting on time. I will attach the tune and log below. I have tried reducing shift times, I have adjusted oncoming and offgoing pressures. I have been having issues with this car doing this, if anybody has any feedback or pointers I can try pls let me know. Tia.

    didn't look at everything but shift times faster than .25 are too fast. I also wouldn't disable all torque management, but some make it work that way.

    How the fluid level?

    Tried overfilling the transmission slightly to make sure it's not starving for fluid?
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Be sure that when you change the oncoming pressure that you go through the relearning process. I was tuning a 6l80E in a Silverado and it wasn't shifting on time, so I logged fuel cut type and it said "TqRed". I fixed the issue by lowering the shift RPM. There's probably something else you can change to fix this but at the time I couldn't think of anything. I tried changing some TqMgt settings but no luck so I just lowered the shift RPM. I posted two screenshots of the truck and the Camaro it seems to be the same thing. If you find another way to fix this issue please post about it.
