What's the flavour? Everything but RAW will auto scale according to what you drive.
Raw default settings will give you a lot of clipping. It's too much signal strength for the G29, so you'll lose a lot of detail. See the ffb graph (bottom left of telemetry HUD) and reduce tone and volume til you stay below the red bar.
Btw there is no "clipping noise". Clipping is when the wheel is at max load so it flat lines. Any signal above the max load of the wheel is "clipped".
