Ill answer both of the above question here. theory- 3 banger at 3200rpm=a 4 banger at 2400rpm on terms or power, frictional loss and yes even injector firing (3 injectors firing at 3200rpm=4 injectors firing 2400 rpm) Now that the injectors are injecting the same, like a underdrive pully, everything else is turning slower (alt,water pump, etc)
