last night I did some experiments with my CH pedal, by previous yaw sensitivity setting is 100% which works good with most of XP planes. but not TBM.
I tried %0, %10, %20, %30, %50, %100 those sensitivity settings, finally I found < 50% will dramatically ease your high speed ground handling.
my testing steps:
1. advance my throttle smoothly, keep ~30% TRQ, wait for air indication speed alive
2. when speed is around 50knots, I cancel my throttle to flight idle, then taxi range, then reverse range gently.
roughly I can follow a long straight line. finally I select 10% yaw sensitivity setting for this TBM. hope it works on your side
