Again some situations will warrant its use but in general and daily driver use the perceived gains are greater than the real ones.

Not according to our data - the thermo opening up at 180 vs 209 has not had any "pissed" off effects on the ECU at all - in fact all the notions that the oil pressure and/or MPG will go down has not translated to any data we have accrued.
We would agree that more engine load would constitute more cooling such as a SC. But consider guys that tow or race full throttle the same category and the THERMO opening sooner will give the cooling system more time to fight off heat. This in conjunction with a now ready Diablo tuner will allow you to turn on the fan sooner and dissipate heat.
