What are performance effects of calif emissions on the 2012 Grand Cherokee Laredo V6 4x4? What emissions equipment (catalytic converter) are different from Calif to non-Calif vehicle? Is there a horsepower difference at the wheels?
Does anyone know the actual difference between NAE, California emissions and NAS, 50 state emissions?
Is it just a different sticker?
Or possibly different computer code in the ECU?
