Does anyone know of a tuner or reprogramming that can adjust when the cooling fan and grill shutters come on? I want to lower the temp as the factory setting is pretty high IMO. 5th gen 2020 1500DT

If you can't find tuner to do so then its time to remove a few of the shutters for more air flow top the radiator...Does anyone know of a tuner or reprogramming that can adjust when the cooling fan and grill shutters come on?

You'll need an unlocked PCM and the bypass cable to use a tuner on it to adjust the fan setting.Not cheap to do.You can throw a 190 thermostat in with no issues,you could even drop down to a 180 thermostat,but a 190 is a good middle of the road thermostat.Does anyone know of a tuner or reprogramming that can adjust when the cooling fan and grill shutters come on?
