Serious?
You already have 2 other thread about pretty much this same topic.
Having us tell you that the mods you want to run are wrong are clearly NOT sticking in your head. Clearly you have not done any research either, so all of this is going nowhere fast.
Does it really? It might just feel that way because it can't take away anything because it doesnt know its knocking.I know the thermostat won't add horse power but it helps keep the motor cooler resulting in more power.
Colder air and fuel mixture make more power, not a cold motor.
