How about grounding direct to ground with a steel cable dragging around under the truck?

I have no idea if grounding the TB helps or not, don't really care.
I can come up with one possibility on why it might make a difference. With a floating(electrically) TB I could see electrical noise being generated on a position sensor, which could result in an incorrect or slowly filtered analog to digital conversion reading by the ECU. Grounding the TB would in effect shield the sensor and reduce noise on the sensor ADC lines and in effect reduce the feedback loop time between the position sensor and the butterfly.
Its all speculation though as I have no idea if any sensors even exist inside the TB. I am not going to do it personally, but I could think of one possible effect and thought I would stir the pot.
