Sorry to bring a thread back from the dead...
The reason coolant flows though the TB is to keep the TB from freezing and sticking.
At the rate the air is moving through the TB it could freeze over.
Really only usefull during winter.
While there is a cooling affect due to the air pulling past the TB, it is nowhere near great enough to initiate freezing. In the few datalogs I have done in the last week or 2, I have never seen the ACT temp get below 100F, once the engine is warm. I don't have the large heat sink of an upper intake either, meaning the long runner style. I am using a box style Comp Polymer intake.
When the engine is cold, the coolant is cold as well, so the affect of coolant would be minimal for preventing freezing of the TB.

i never EVER had problems after eliminating the coolant lines from the throttle body. The throttle body area did feel much cooler with them removed.
Are you still running the egr? Are you sure that the system is fully functional?
If you have hot exhaust gasses running through the intake, the coolant should help to cool things back down.
Are you comparing both before and after coolant line removal @ full hot conditions, or atleast similar conditions?
I am not trying to argue, just want to understand what is really going on.
