Theory: There 2 coolant hoses that connect to the bottom of the TB. They heat up the TB in winter when it is cold (coolant is hot comming from the engine).

What i did is unplug them both from the TB. then i took one (hoseA) of from the other end and i connected the other (hoseB) hose to where (hose A) used to connect(not the TB end).

This should reduce the TB temperature keeping it cool. And since air flows though there, it'll stay colder and give more power (very little but with the EGR and PCV, it might add up to something!)
