    Nag1 shift delay?

    So, on my 13 300c 5.7 I changed the rpm shift points to 6k rpm and cut offs at 6200rpm. when I was testing the tune, it felt like it was bouncing on the limiter or had hesitation for a second or two before it actually shifted. Any ideas? I haven't done a data log but here is my current tune. Any help is appreciated.

    I am not very good with the tuning side of things, but to me this looks like torque management kicking in. Hopefully someone else can help on how to change the tune to stop it from doing that.

    Again, please keep in mind that I don't know much about tuning, I specialize the transmission itself, but I am trying to learn and maybe help too. To me this still looks like what you feel is torque management kiciding it. Look at this screen shot where the light blue line is the accelerator pedal, the orange is the throttle plate and the light green is the engine RPM. You can see it dropping the throttle before it shifts, I am thinking that is what you are feeling. TM.png
