I drive on P500 M mode all the time from the start on my 6 sp MT. I don't wait for the engine to "warm up". I use P400 only on long avenues with multiple lights and with traffic almost stopped to a stand still.
I NEVER drive unless that Power button is illuminated.Anybody drive in "M" mode and with the power button on for daily driving?
Is this just overkill for daily street driving?
Is gas mileage much different without either on?
