Making more room for fast revving at gear changes:
- Raised Cutoff by 200 rpm: Engine Fuel Cutoff DFCO Cutoff vs RPM
- Raised cam disable by 300 rpm: Engine Airflow Variable Camshaft Hi RPM Disable
- Lowered Transmission torque management by 50% at WOT — Transmission Torque Management — Adder Modifier -0.50 at RPM 4500
Resulting shift 1-2 took 0.3sec then 0.4s on 2nd test. Need to retest cold due to the engine making more power cold.

Interesting consistency that IAT2 uniformly starts ~30F and ends ~40F hotter than IAT1 regardless of ambient. This suggests a way to check effectiveness of changes to the intercooler cooling system. Other runs show a end range of 40-47F.
