Bravo. You must be inhaling the good stuff if your gonna start comparing yourself to every other non-educated person.
As for removing the thermostat, your gonna run the engine over cool. You will end up with bad fuel economy since the CTS will assume the engine is not at the normal operating temperature and inject more fuel. This causes premature engine wear as the excess fuel will wash the oil from the cylinder bores. So no matter how much you think your car is properly maintained and soundless, you're screwing it up. If you still think the direct system is a good way, keep at it. Don't advice others to do the same.
