I first loaded the 87 octane tune from the Trinity. I heard spark knock, logged it, and it showed a good bit of knock retard. I can try this again and send you a plot if you are interested. Shifted pretty hard, felt like torque managment was disabled, but I did not log that spark parameter. I want to do some more testing later because it seemed I had more power, but I was suprised at how much knock I got with the 87 tune.
I then datalogged the stock tune and it showed knock retard, so I started taking a slight bit of timing out (from stock tune!) and barely added richness (even though I though AFR looked fine).
I then tried to disable the Torque Management (selected "OFF" on the Trinity for "Upshift TM ON/OFF"). It didnt seem to shift as hard as the 87 tune did.
Datalog showing TM is still taking out timing. I attached my most recent tune and log. Can you please check it and let me know.
