A colder than normal thermostat can add power to some engines by allowing more ignition timing and improved air fuel ratios to be delivered by the computer. Some research will be required to get the correct upgraded thermostat for your car, but dropping the coolant temperature by some 10 degree celcius can give a decent result.
really? coz the mechanic took mine out n the reading on the dashboard became really low! so it s a good thing?
